Finding the right nanny or in-home caregiver starts with verifiable credentials, background clearance, and a systematic hiring process that catches problems before they begin. Your primary tools are checking current CPR and First Aid certification, conducting thorough background screening, speaking directly to past employers by phone, and watching for behavioral red flags in both the candidate and your child. This guide walks through the specific qualifications to require, the screening steps that actually protect your child, the legal responsibilities you carry as an employer, and the warning signs that mean you need to act immediately.

Essential Certifications and Qualifications
Current CPR and First Aid certification covering infants, children, and adults is the most important qualification you can verify. The Red Cross and American Heart Association are reputable organizations whose certifications must be renewed every 2 years—meaning a certificate dated more than 24 months ago is expired. No federal license is required to work as a nanny, which is why certifications become your primary credentialing tool.
A high school diploma or GED is the standard baseline education for nannies. Beyond that, formal childcare training of at least 20 hours is considered standard practice, though it varies by employer preference. Some candidates have taken infant CPR-only courses, which are insufficient—they must cover children and adults as well. Optional but highly valued is the Certified Nanny credential, which requires 2,000 documented hours of childcare experience.
This is not a legal requirement but signals serious professional commitment and is often required by nanny agencies. Ask to see the current certification card itself, not just a verbal claim. Ask when the CPR certification expires and request a photo of the card. If the candidate cannot produce it immediately, decline to proceed. Expired certifications mean the person has not renewed required training in critical emergency skills.
A nanny with 20+ hours of formal childcare training has studied child development, age-appropriate activities, nutrition, and basic health indicators that an untrained person would miss. Agencies often provide or require this training; independent candidates may have completed it through community colleges or online programs. during your interview, ask the candidate to describe their approach to infant CPR or a choking situation.
A prepared answer shows they have thought through emergencies. Vague responses or hesitation are reason to ask for detailed clarification or move on.
Running a Thorough Background Check
background screening must include criminal records, searches of abuse registries, and credential verification—not simply a basic employment check. Requirements vary significantly by state; California requires ICRAA-compliant screening with written consent, while other states mandate FBI fingerprint checks or annual rescreening.
The specifics depend on where you live. Background screening typically costs $30–$150 per hire and should include all of the above elements. This is more extensive than standard employment screening because children's vulnerability demands higher scrutiny. The cost is non-negotiable and should be factored into your hiring budget. Research your state's specific requirements before choosing a screening service.
Some states require applicants to consent in writing; others mandate FBI fingerprinting; a few require annual rescreening while employed. If you use a nanny agency, they typically conduct the check—verify what they are actually checking, not just assume. Do not use generic employment screening sites—they were not designed to check abuse registries or specialized childcare disqualifications.
Use services certified for nanny screening or consult your state's child welfare agency for approved vendors. A clean background check means no convictions for crimes against children, no substantiated reports of abuse or neglect, and no false credentials. But a background check is a snapshot of the past. It does not predict current behavior, judgment, or how the person treats children in private.
Assume the person knows you will screen them. If they become defensive about the process, mention their past criminal activity that was not severe, or refuse to consent to screening, these are serious red flags. A trustworthy candidate expects this and cooperates.
Verifying References With Direct Conversation
Verify at least three references by phone from the candidate's two most recent families plus one additional reference, corroborating phone numbers independently through Google search to confirm they match legitimate former employers. People may withhold concerns in writing but share them in conversation, which is why phone calls are mandatory.
Do not accept references only by email or text. Written communication is easily faked and allows the candidate to rehearse responses with the person. A phone call creates accountability and often surfaces hesitation or genuine candor that typed messages hide. When you call, ask: "How long did candidate] care for your child? What ages? What was their greatest strength? If you could change one thing, what would it be? Would you hire them again?" Listen for hesitation before "yes" answers.
Genuine enthusiasm sounds different from guarded politeness. Ask about punctuality, how they communicated about your child's day, how they handled conflicts, and whether your child was happy to see them. Probe any vague answer. "They were fine" is different from "My child loved her and I trusted her completely." If a reference expresses concern about anything—even small things like arriving late or being on their phone—take that seriously.
[An inability to provide verifiable recent references, frequent unexplained job changes, or persistent negativity about former employers indicate possible professionalism, boundary, or accountability issues. Corroborate phone numbers by searching the employer's name and the nanny agency or family website independently. One parent once gave a reference number that was the candidate's own phone—a common fraud.
If you cannot verify the reference independently, do not count it. Ask permission to contact additional references beyond the three you are given, and actually follow up. Families who rehire are the gold standard; those who will not recommend the candidate or went silent are meaningful signals.
Red Flags During the Hiring Process
An inability or unwillingness to provide verifiable recent references is a serious red flag, as is a resume full of brief stints with unexplained gaps or vague reasons for leaving. Legitimate candidates can explain their job history. "I left to try something different" is acceptable; "My former employer was difficult" repeated across multiple jobs warrants investigation.
Resist pressure to hire quickly or skip steps. A good candidate is not offended by thorough screening. If someone pushes back against background checks, reference calls, or multiple interviews, that impatience is itself a red flag—it suggests they know something you will find. Persistent negativity about former employers, especially if the candidate blames every family for the departure, indicates a possible pattern of boundary or accountability issues.
Most nanny-family separations are neutral; consistently harsh judgment suggests the candidate does not take responsibility for conflict. If the candidate cannot articulate their approach to discipline, managing tantrums, or keeping a child safe during an outing, move on. Prepared answers show they have done this work before. Vagueness suggests they have not thought it through or are hiding how they actually respond to stress.
A candidate who cannot provide recent references (from the past 2–3 years) is concerning. Old references do not speak to their current approach or reliability. If they left their most recent job under unclear circumstances, ask directly: "Why did you leave? What happened?" Watch for inconsistencies between their resume and their interview answers. If they claim five years at one family but the reference from that family is unclear or does not match the timeline, probe the discrepancy.
Behavioral Warning Signs After Hiring
After hiring, watch for late arrivals, excessive early absences, phone focus instead of active engagement with your child, or avoidance of discussing the child's day—these indicate reliability and safety concerns. A nanny who is chronically late creates scheduling stress and suggests they do not prioritize your family. A pattern of calling in sick or leaving early is reason to address it directly.
Excessive phone use during work hours, especially when alone with your child, is a red flag. A nanny should be attentive to the child, not scrolling social media, texting, or taking calls. You can install a nanny cam or simply observe—if they are always on their phone when you arrive home, that is not the person you hired.
An unwillingness to discuss your child's day is concerning. A reliable caregiver gives specific updates: what they ate, how long they napped, what they did, any concerns. Vague responses like "Fine, they were good" suggest they are not engaged or are hiding something. Sudden changes in behavior are worth noting: becoming secretive about their phone, leaving the room when you enter, or shifting their schedule requests.
These can indicate they are looking for another job or are uncomfortable with your oversight. A nanny who becomes defensive when you ask questions about your child's care or your parenting decisions is a warning. They should be collaborative, not adversarial. Professional caregivers understand they work for you. If your child asks to use the bathroom constantly when the nanny is present, requests to be alone, or suddenly expresses fear of the caregiver, stop and listen.
Children do not usually lie about their comfort with caregivers. Investigate the reason—it may be something innocent, but it requires direct conversation with your nanny and possibly a meeting with your pediatrician.
Your Child's Behavioral and Emotional Response
If your child suddenly displays anxiety, fearfulness, withdrawal, excessive crying at the nanny's arrival, sleep disturbances, or aggressive behavior, something is wrong and warrants immediate investigation. These behavioral changes are your child's communication of distress, even if they cannot tell you in words. A child who was previously happy to see their caregiver and suddenly clings to you or cries is signaling discomfort.
This does not always mean abuse, but it does mean something has changed and needs attention. Do not dismiss it as "a phase." Sleep disturbances, nightmares, or fear of being left alone can indicate anxiety triggered by the caregiver or something that happened during care. Aggressive behavior toward siblings or sudden regression in toilet training can also signal emotional distress.
Listen without judgment if your child mentions the nanny made them uncomfortable, touched them in a way they did not like, or said something mean. Children sometimes misinterpret things, but they do not usually fabricate. Take every mention seriously and investigate. Meet with your pediatrician if your child shows significant behavioral changes. A doctor can assess whether the changes are developmental or something triggered by stress.
They can also advise on next steps and whether to contact authorities. A temporary adjustment period is normal—a new caregiver requires time. But if behavioral changes persist for weeks or escalate, the caregiver may not be right for your child or may be causing harm. Trust your instinct. If something feels wrong, it probably is. You do not need absolute proof to make a change; parental intuition is part of responsible caregiving.
Your Legal and Financial Responsibilities
Families are employers (not independent contractors) and must carry liability insurance with at least $1 million limits and workers' compensation insurance, which is legally required in many states. Misclassifying a nanny as an independent contractor via 1099 forms can result in tax evasion charges for you, the employer. If you do not classify your nanny correctly, you risk federal and state tax penalties, fines, and legal exposure.
The IRS and state labor departments take nanny classification seriously because caregivers are often underpaid and under-protected when incorrectly classified. Liability insurance protects you if your nanny is injured on the job or if your child is injured while in the nanny's care. A $1 million minimum limit is standard; your homeowner's policy typically does not cover household employees.
Ask your insurance agent to add a domestic employer policy. Workers' compensation insurance covers medical expenses and lost wages if your nanny is injured while working. This is legally required in most states and is the nanny's primary recourse if an injury occurs. Skipping it leaves both you and the nanny unprotected. Pay your nanny on a documented schedule and keep records.
Consistent payment and clear documentation protect both of you. An under-the-table cash arrangement leaves no paper trail and creates liability if anything goes wrong. Consult a tax professional or use a nanny payroll service to handle the paperwork. These services calculate and file taxes, ensuring compliance with federal and state requirements. The cost is usually $500–$1,500 annually and is far cheaper than tax penalties.
Put your agreement in writing, including hours, pay, benefits, sick days, vacation, and grounds for termination. A written agreement prevents misunderstandings and protects you both. Have an attorney review it if your situation is complex.
The Interview Process and Assessment
During your interview, ask behavioral questions that reveal how the candidate handles real situations: "A toddler refuses to get in the car seat. What do you do?" "You find the baby has a fever. Walk me through your steps." Prepared answers show experience. Observe how they interact with your child during the interview. Do they get down on the floor? Make eye contact? Ask your child questions? Someone genuinely skilled at childcare naturally engages with children.
Ask about their approach to discipline, boundaries, and screen time. Do their answers align with your parenting philosophy? A nanny whose methods clash with yours will create conflict and confuse your child. Discuss your expectations for communication. Will they text you updates? Call if there is an issue? How will you handle disagreements about care? Clear expectations prevent misunderstandings later.
Ask what they would do in an emergency: a severe allergic reaction, a fall with possible head injury, or a choking incident. Their answers should be calm, specific, and safety-focused. Conduct at least two interviews before hiring, ideally with your partner present so you both assess the candidate. Trust your gut feeling. If something feels off, it probably is.
Request a trial period—the first week or two—where you are home or nearby. Observe how they interact with your child, how they communicate with you, and how they handle transitions. This trial gives you a low-risk way to confirm your choice before committing long-term.
Ongoing Monitoring and Communication
Establish a clear communication system with your nanny: daily updates about feeding, sleep, activities, and any concerns. The more specific the better. Written updates (via text or an app) create a record and ensure nothing is missed. Use a nanny camera for peace of mind, especially during the first weeks. Nanny cameras are now affordable and easy to set up.
Make sure you have informed consent from your nanny—transparency prevents trust issues later, and consent is legally required in many states. Have regular check-in conversations, not just about your child but about how your nanny is doing. Is the schedule sustainable? Do they need support or resources? A caregiver who is stressed or unhappy will not perform well.
Keep detailed notes about your child's development, behaviors, illnesses, and any incidents involving the nanny. These records are invaluable if you ever need to address a concern or if a situation escalates. Schedule periodic reviews—monthly at first, then quarterly—to discuss how things are going, adjust expectations, and address any concerns before they become problems. Constructive feedback helps the nanny improve and shows you are paying attention.
Maintain a professional relationship. Be appreciative of good work, set clear boundaries, and do not discuss personal problems or treat the nanny as a friend or therapist. Blurred boundaries often lead to conflict. If you notice concerning behavior or your child reports something troubling, address it immediately. Do not wait, hope it improves, or assume you misunderstood. A direct conversation often resolves small issues before they become serious.
When Something Goes Wrong
If you suspect your child has been harmed—physically, sexually, emotionally, or neglectfully—contact your pediatrician and your local child protective services immediately. Do not delay waiting for more information. Trained professionals can assess your child and guide next steps. Most families who end a nanny relationship do so amicably, due to schedule changes, relocations, or a sense that the fit is not right.
If that is your situation, provide notice (typically 2 weeks), pay any unused vacation, and end professionally. If you suspect abuse or serious misconduct, you may terminate immediately without notice. Contact authorities before or immediately after terminating the relationship. Do not confront the nanny about abuse allegations alone—have a third party present or call the police if you believe a crime has occurred.
Document everything: save text messages, emails, notes about incidents, and records of conversations. These documents may be needed if you file a report or face any legal questions. Understand that mandatory reporters (including you, as an employer) are often legally required to report suspected abuse to child protective services or law enforcement. Failing to report can be a crime.
If you terminate a nanny, consider whether you have any legal or financial obligations: unused vacation days, severance, or final paychecks. Consult an employment attorney if the situation is complex or contentious. Many families experience anxiety after a nanny leaves, even when the separation was appropriate. This is normal. Focus on your child's wellbeing and what comes next—whether that is a new nanny, a different childcare arrangement, or a new schedule.
Frequently Asked Questions
What should I look for in a nanny's certification?
CPR and First Aid certification covering infants, children, and adults is essential and must be renewed every 2 years from reputable organizations like the Red Cross or American Heart Association. Ask to see the current card itself. Expired certifications mean required emergency training has lapsed.
How much should background screening cost?
Background screening typically costs $30–$150 per hire and should include criminal records, abuse registry checks, educational credential verification, and employment reference confirmation. This is more extensive than standard employment screening because children's vulnerability demands higher scrutiny.
How do I verify references if the candidate gives me only written recommendations?
Do not accept written references alone—they are easily faked and allow the candidate to rehearse responses. Call references by phone and corroborate phone numbers independently through Google search to confirm they are legitimate. Ask about punctuality, communication, and whether they would rehire the candidate.
What should I ask during the interview?
Ask behavioral questions about real situations: "A toddler refuses the car seat—what do you do?" or "You find the baby has a fever—walk me through your steps." Observe how they interact with your child and discuss your expectations for communication and discipline.
What red flags should I watch for after hiring?
Late arrivals, phone focus instead of engagement, unwillingness to discuss your child's day, or sudden behavioral changes in your nanny are warning signs. If your child suddenly displays anxiety, fearfulness, excessive crying at the nanny's arrival, or sleep disturbances, investigate immediately.
Do I need to carry insurance for my nanny?
Yes. You must carry liability insurance with at least $1 million limits and workers' compensation insurance, which is legally required in many states. Correctly classify your nanny as an employee, not a 1099 independent contractor, or you risk federal and state tax penalties.
