Your baby's first day at daycare will likely go smoothly—many children find the new environment interesting at first—but expect days 3–4 to become harder as your child realizes the routine is staying. This is a normal adaptation, not a sign something is wrong. Separation anxiety can begin as early as 9 months and intensifies between 18 months and age 3, so your baby's reaction depends heavily on age and temperament, but all of this is expected and manageable with preparation.
Parents often worry most about what they cannot see: whether their baby will eat, sleep, and stay safe without them. Daycare providers are trained to manage these transitions, and you can support the adjustment by understanding what to expect each day, what to bring, and which changes are normal. Most children settle into daycare within the first 1–2 weeks, though the timeline varies.

The First Day: What Actually Happens
Your baby will likely have a quieter morning than usual because of the change in routine and your own anxiety, which children pick up on immediately. Arrive early enough to let your child explore the space, meet the provider, and see the toys and other children.
Do not rush the goodbye—a quick, matter-of-fact departure is easier on your child than a long, emotional one, but vanishing without saying goodbye creates confusion and makes the next day harder. Most children cry when you leave. This is not a sign daycare is wrong for your family; it is a sign your child is old enough to know you are gone.
Providers expect tears and are equipped to redirect the child within minutes. Stay calm, say goodbye clearly—"I will pick you up after lunch"—and leave. Returning to peer through the window or re-entering teaches the child that crying may bring you back. The first day often goes well because everything is novel.
Your child may be engaged with new toys, new adults, and new children for hours. Providers will text or call if there is a medical emergency or if your child is unconsolable for an extended period, but a quiet first day does not mean the adjustment is finished. When you return, your child may be exhausted, cranky, or clingy.
This is normal—the day was stimulating and emotionally taxing. Expect your child to need extra comfort, food, and sleep. Do not be alarmed if your baby sleeps deeply or seems withdrawn; the body processes change by resting.
Separation Anxiety and Your Baby's Age
Separation anxiety emerges between 9 months and 3 years of age, with most intense reactions occurring between 18 months and age 3, according to guidance from children's care sources citing the American Academy of Pediatrics. Infants under 9 months may cry at separation but do not yet understand object permanence, so they experience less acute anxiety about your absence.
Babies 9–12 months show stronger separation anxiety: they know you exist when you are gone, and they worry you will not return. At this age, a calm, consistent farewell routine—the same words, the same goodbye touch—reassures your child that this is predictable and safe. Many 9–12-month-olds adapt within a few days because their anxiety is intense but their memory for worry is short.
Toddlers 12–24 months are often the most distressed group. They are mobile enough to follow you to the door and vocal enough to express their protest loudly. Their sense of time is developing, so "I will pick you up after lunch" does not feel reassuring. They do eventually trust the routine, but the first week may be genuinely hard.
Consistency matters most here: the same arrival time, the same provider, the same routine each day builds the sense that this is safe and predictable. Children 2–3 years often have the language to ask questions: "When will you come back?" and "Will you forget me?" Answer honestly and specifically. "After snack time" is more concrete than "later." Repeating the same explanation each day reinforces that the plan is real and stays the same.
The First Week Gets Harder Before It Gets Better
The first 2–4 days often follow a predictable pattern: the first day or two may go smoothly because the environment is novel, but days 3–4 become harder as the baby realizes the routine is staying. This is not a setback; it is a sign your child understands what is happening. Expect the worst behavior mid-week and a gradual improvement by the end of the first or second week.
On days 3–4, expect your child to cry harder and longer. The novelty has worn off, and your child now associates the space with your departure. This is developmentally appropriate. Providers are prepared for this and will use distraction, routine activities, and comfort measures to help your child settle. They will not call you unless there is a genuine problem.
By the end of the first week, most children show signs of adaptation: they may still cry at goodbye, but they engage with activities more quickly, they eat and sleep better, and they show fewer signs of distress during the day. Some children take two weeks or longer, especially if they are older toddlers or have highly sensitive temperaments.
The second week is often easier than the first. Your child begins to recognize patterns: the same toys, the same songs, the same snack times. Some children will be excited to go to daycare and upset when you pick them up early. Others remain anxious but manage the anxiety better. Both are normal. Watch for regressions after the second week if your child gets sick, you miss a few days, or the staff changes.
Returning to daycare after an illness or absence can feel like starting over because the routine is interrupted. Consistency resolves this quickly.
What to Pack: The Complete Checklist
Pack at least three spare outfits, extra diapers and wipes, labeled bottles or sippy cups with your child's name, a comfort item (toy or blanket from home), a sleep sack or nap blanket, and any special feeding supplies. Label all belongings clearly with a permanent marker or clothing labels to prevent loss. Daycares handle dozens of children daily, and unlabeled items disappear or get mixed up.
Include a weather-appropriate extra layer—a sweater, rain jacket, or hat—because children go outside in most weather, and what you dressed them in at 7 a.m. may not fit the afternoon temperature. Pack socks in a small labeled bag if your child wears them; single socks are lost constantly. Bring any special equipment your child needs: a particular brand of formula, a preferred diaper size, prescription creams for rashes, or hearing aids if applicable.
Do not assume the daycare has what your child uses at home. Provide clear, written instructions for any medication, including the exact dose, frequency, and any side effects the providers should know. Include a change of clothes in your car and a backup set in your diaper bag, because accidents, spills, and outfit disasters are frequent, especially in the first weeks.
Providers will contact you if your child has a major accident, but having extra clothes on hand speeds up the process. Comfort items help with transition. A stuffed animal, a small blanket, or a photo of family from home can soothe a distressed child. Not all daycares allow comfort items during the day—ask your provider—but many let children hold one during nap time.
Health Requirements and Vaccination Records
All U.S. states require child care facilities to keep vaccination records on file, and most exclude children who do not meet state immunization requirements, though enforcement varies. Medical and other exemptions exist per state regulation. Before your baby starts daycare, confirm what your state and facility require. You will need to provide vaccination records, emergency contact information, allergy details, any medication forms, and a second copy of health documents to bring on arrival.
Most daycares require these 2–3 weeks before enrollment. Do not wait until the last minute to gather these documents. Bring the original immunization record from your pediatrician, not a photo or a printout unless the daycare specifically approves it. Include dates for all required vaccinations: hepatitis B, polio, DTaP, measles/mumps/rubella, varicella, and others per your state's requirements.
Some facilities also require a TB test or documentation of tuberculosis screening. Complete all medical forms the daycare requests: an emergency contact list, an allergy form, a medication authorization form if your child takes any medications, and a health history. Write clearly and provide your phone number, a backup contact, and the pediatrician's number. Providers need to reach you quickly in a medical situation.
Bring proof of a recent physical exam (within the past year) if the daycare requests it. This visit documents that your child is healthy and developing normally, and it flags any conditions providers need to know about.
Expect Illness: How Many Infections Are Normal
Children in their first year at daycare experience significantly more illnesses than children cared for at home. A 2026 UK study found toddlers in their first year of nursery experience approximately 15 illnesses, including 12–15 respiratory infections, 2 gastrointestinal illnesses, and 1–2 skin-rash infections such as roseola. Risk is highest before age 2. This is not a sign the daycare is unclean; it is a statistical fact of group settings.
Most of these illnesses are mild: colds, mild fevers lasting a few days, and rashes that resolve on their own. Severe infections requiring hospitalization are rare. Providers are trained to recognize signs of serious illness and will contact you immediately if your child develops a high fever, difficulty breathing, or other warning signs. Colds and upper respiratory infections are the most common illness in daycare.
Your child may have a runny nose, mild cough, or low fever for a few days, then recover. Some children get multiple colds in rapid succession during the first few months, and this is normal. Over time, your child's immune system recognizes these viruses and fights them off faster, so the severity and duration of colds typically decrease.
Some research suggests children who attend daycare in infancy may experience fewer infections by school age, possibly due to early immune exposure—sometimes described as an "immune boot camp" effect—but this evidence comes from longitudinal studies and is not universally accepted, and early childhood illness should not be the reason to expose infants to germs. The benefit is not guaranteed. Keep your child home when sick to prevent spreading illness to other children and to give your child's body time to recover.
Most daycares require children to stay home until they have been fever-free for 24 hours without fever-reducing medication and until any rash is healing. Ask your provider for the specific exclusion policy.
Sleep, Feeding, and Bathroom Routines
Your baby's sleep schedule at daycare will be set by the provider and typically follows a rhythm of morning snack, lunch, nap, afternoon snack, and play until pickup. Even if this differs from your home routine, try not to disrupt it—consistency helps your child adapt faster. Most daycares follow structured routines precisely because routines help children feel secure.
Feeding depends on your baby's age. Infants under 6 months receive bottles according to hunger cues or a schedule you provide. Older babies and toddlers eat meals and snacks with the group. If your child uses a bottle or sippy cup at home, provide labeled ones at daycare. Providers will not give bottles or sippy cups without the parent's consent, so bring clearly labeled containers.
Some children refuse to eat much on the first day or two, either from stress or from unfamiliarity with the new setting. This usually resolves within a few days as the child settles. A child who eats little on day 1 will often eat normally by day 3 or 4. Providers will let you know if a child is not eating enough to be concerning.
Nap time is a major transition. Your child may not nap well at daycare initially, especially if napping is different from home. Some children eventually sleep better at daycare because of the routine and the presence of other sleeping children. Others take weeks to relax enough to sleep. A child who does not nap may be tired and cranky at pickup; this improves as the child adjusts.
Toilet training complicates the transition if your child is in that stage. Daycares vary in their readiness to support toilet training; some will not begin until a child shows clear signs of readiness, and others will work with the parent's plan. Discuss this with your provider before starting if it is relevant to your child.
How Providers Communicate Updates
Most daycares use a digital app or a paper log to send you updates on your child's day: meals eaten, diaper changes, nap duration, mood, and activities. This provides peace of mind and helps you understand your child's experience. However, do not expect detailed narration of every moment; providers are managing multiple children and cannot document everything in real time.
Some facilities send photos or videos throughout the day, and others send a summary at the end of the day. Clarify the provider's communication policy before the first day so you know what to expect. If you have a preference, ask—some parents find constant updates reassuring, and others find them anxiety-provoking. Providers will contact you immediately if your child is injured, develops a high fever, has a severe allergic reaction, or is inconsolable despite their efforts to comfort.
Do not ignore a call or text from daycare during the day; these are always important. Keep your phone accessible and make sure your emergency contact information is current. The first few days, your child's provider will likely give you a verbal update at pickup: how your child ate, slept, and handled separation. Listen to these details; they help you understand your child's experience and identify patterns.
If your child cried for hours, ate little, or seemed distressed, the provider will tell you. As your child settles, the daily updates may become less detailed because the experience becomes routine. This is normal and a sign your child is adjusting. If you have concerns, ask specific questions at pickup or send a message through the app.
Signs Your Baby Is Adjusting vs. Warning Signs
Most children show the same pattern of adjustment: harder first week, gradual improvement in week 2, and increasing comfort by week 3 or 4. By the end of the first month, most children go to daycare without tears, engage in activities, eat and sleep reasonably well, and show happiness when they see familiar providers. Regression is normal during sickness, schedule changes, or staff transitions.
A child who was doing well may suddenly cling and cry when you leave. This usually passes within a few days as routines stabilize. If regression persists for more than a week without an obvious trigger, mention it to the provider and your pediatrician. Warning signs that warrant a conversation with the provider include: your child is not eating enough to gain weight normally, is sleeping so much that the provider cannot engage them, shows signs of abuse or unusual injury, or is withdrawn and unresponsive even after the first week.
These are rare, but they are reasons to ask questions and possibly seek a different care setting. If your child's mood at home becomes persistently negative—refusal to go to daycare, excessive clinginess, sleep disruption, or aggression—discuss this with your provider and pediatrician. Most often, this is a temporary adjustment reaction, but it is worth monitoring.
Your child may regress in toilet training, show increased tantrums, or have nightmares during the adjustment period. These are stress responses and usually resolve within a few weeks as the child's sense of safety returns. Maintain patience and consistency; do not interpret these as signs that daycare is wrong.
Building the Transition: What You Can Do Before Day 1
Visit the daycare with your child before the first day if possible. Walk through the rooms, introduce your child to the provider, and let your child see the toys and outdoor space. This familiar visual helps on day 1 because the space is not completely strange. Some children remember the visit and feel less alarmed on the first day.
Read books about starting daycare with your child if they are old enough to understand. Stories like *The Kissing Hand* or *I'm Going to Daycare* normalize the experience and give your child language to process the transition. Even very young children respond to the rhythm and pictures of a familiar book. Talk about daycare positively in the weeks before.
Use simple, honest language: "You will stay with Ms. Sarah while Mommy works. I will pick you up after snack time. You will play with toys and other children." Avoid suggesting daycare is a punishment or a scary place, even if you are anxious. Practice short separations at home with a trusted adult before daycare starts.
Leave your child with a grandparent or babysitter for 15 minutes, then return exactly when you said. These short, successful separations show your child that you always return and that being with another adult is safe. On the first morning, keep your routine calm and on time. Rush and anxiety are contagious; if you are stressed, your child will sense it and become more stressed.
Arrive a few minutes early so you are not rushing. Let your child bring a comfort item if allowed. Say goodbye clearly, and then leave promptly. Your calm, confident demeanor tells your child that this is safe and normal.
Frequently Asked Questions
Will my baby forget me if I leave them at daycare?
No. Babies and toddlers do not forget their parents or primary caregivers. Separation anxiety is a normal developmental phase that shows your child understands you exist when you are not there, and it does not reflect how much your child loves you or remembers you. Your child will be excited to see you at pickup most days, even if they cried when you left.
How long does the crying usually last?
Most children stop crying within a few minutes after the parent leaves, though some may cry intermittently throughout the day the first few days. By the end of the second week, most children cry less or not at all at goodbye. If your child is crying for hours despite the provider's comfort efforts, discuss this with the provider—it may mean your child needs extra transition support, a later start date, or a different care arrangement.
What should I do if my child refuses to go to daycare?
Resistance is common but usually temporary. Keep the routine consistent, acknowledge your child's feelings ("I know you do not want to go, and we are going anyway"), and make the goodbye quick and calm. Bribing or negotiating often makes resistance worse. Most children accept the routine within a few weeks. If resistance continues for over a month, discuss it with your pediatrician and daycare provider.
Is it normal for my child to get sick soon after starting daycare?
Yes. Toddlers in their first year of daycare typically experience approximately 15 illnesses, with the majority being respiratory infections. Most of these are mild colds that resolve in a few days. Ensure your child's vaccinations are up to date to reduce the risk of serious illness.
Should I stay at daycare the first day?
It depends on your provider's policy and your child's temperament. Some daycares encourage a brief parent visit so the child can explore while you are present. Others ask parents to leave immediately so the child does not experience prolonged separation. Ask your provider what works best for your child and your facility.
What if my child has not eaten or napped by pickup on the first day?
This is common and usually not a concern. Children often do not eat or nap much on the first day due to stress and novelty. By day 3 or 4, most children eat and sleep normally. If your child continues to eat or sleep very little after the first week, mention this to your provider and your pediatrician.
