Behavioral development varies greatly from child to child. If you have noticed baby or toddler regressing after starting daycare, here is what you need to know.
The short answer
Some behavioral regression when starting daycare is very common and expected. The transition to daycare is a major life change for a young child, and temporary regression is their way of coping with the stress of separation, a new environment, and a new routine. Common regressions include: increased clinginess, sleep disruptions, potty training setbacks, more tantrums, changes in appetite, and wanting a bottle or pacifier again. Most children adjust within 2-6 weeks. Consistency, patience, and a warm goodbye routine help ease the transition.

What Parents Should Know
According to AAP, NIH guidelines, some behavioral regression when starting daycare is very common and expected. The transition to daycare is a major life change for a young child, and temporary regression is their way of coping with the stress of separation, a new environment, and a new routine. Common regressions include: increased clinginess, sleep disruptions, potty training setbacks, more tantrums, changes in appetite, and wanting a bottle or pacifier again. Most children adjust within 2-6 weeks. Consistency, patience, and a warm goodbye routine help ease the transition. At 0-12 months, babies starting daycare may show changes in sleep patterns, feeding behavior, and overall fussiness. Separation anxiety peaks around 8-10 months, making this a particularly challenging time to start daycare. You may notice your baby is clingier at drop-off and pickup, sleeps differently at home, or has changes in feeding patterns. Bring familiar comfort items (a blanket or lovey) to daycare. Ask about the daycare's routine so you can mirror it at home for consistency. Most babies adapt within 2-4 weeks, though some take longer. It is generally considered normal when increased clinginess during the first 2-6 weeks of daycare. However, you should contact your pediatrician promptly if your child has signs of being mistreated: new fearfulness, unexplained injuries, dramatic personality changes.

Babies starting daycare may show changes in sleep patterns, feeding behavior, and overall fussiness. Separation anxiety peaks around 8-10 months, making this a particularly challenging time to start daycare. You may notice your baby is clingier at drop-off and pickup, sleeps differently at home, or has changes in feeding patterns. Bring familiar comfort items (a blanket or lovey) to daycare. Ask about the daycare's routine so you can mirror it at home for consistency. Most babies adapt within 2-4 weeks, though some take longer.
1-3 years
Toddlers starting daycare often show regression in multiple areas: sleep (nighttime waking, nap refusal), potty training (accidents after being trained), eating (pickier or eating less), behavior (more tantrums, hitting), and social (increased clinginess, separation anxiety). They may also bring home challenging behaviors learned from other children. These regressions are temporary coping mechanisms, not permanent setbacks. Help your toddler by: creating a consistent goodbye ritual, validating their feelings ("I know you miss me"), maintaining routines at home, providing extra connection time after pickup, and not introducing other big changes simultaneously.
What to Tell Your Pediatrician
- Describe when you first noticed baby or toddler regressing after starting daycare and how it has changed over time.
- Note your baby's current age and which age-specific patterns you are seeing.
- Mention if regression is lasting beyond 6-8 weeks with no improvement.
- Mention if your child seems fearful or distressed (not just sad) about daycare.
- Let your doctor know if you have noticed any related concerns, such as changes in feeding, sleep, or movement patterns.
- Bring a list of any questions or observations you want to discuss at the appointment.
What Should You Do?
When to take action
- Increased clinginess during the first 2-6 weeks of daycare

- Wanting more comfort items (pacifier, lovey, bottle)
- Regression is lasting beyond 6-8 weeks with no improvement

What You Can Do at Home
- Keep track of when you notice baby or toddler regressing after starting daycare — noting the time of day, duration, and any triggers can help your pediatrician.
- Remember that increased clinginess during the first 2-6 weeks of daycare — this is generally within the range of normal.
- At 0-12 months, focus on observation rather than intervention unless your pediatrician advises otherwise.
- Respond consistently and calmly to your baby's behavior. Maintain predictable daily routines.
- While monitoring at home, seek immediate care if your child has signs of being mistreated: new fearfulness, unexplained injuries, dramatic personality changes.

Baby Separation Anxiety
Separation anxiety is a completely healthy sign that your baby has formed a strong attachment to you. It typically begins around 6-8 months, peaks between 10-18 months, and gradually eases by age 2-3. It means your baby's brain has developed enough to understand that you exist even when they cannot see you, but not yet enough to understand that you will always come back.
Toddler Regression After a Move or Big Life Change
It is very common for toddlers to temporarily regress after a major life change such as a move, the arrival of a new sibling, starting daycare, a parent returning to work, or changes in family structure. Regression means your toddler may revert to earlier behaviors - having potty accidents after being trained, wanting a bottle again, increased clinginess, sleep disruptions, or baby talk. This is a normal stress response, not a sign that development has been lost. With patience, routine, and emotional support, most regressions resolve within a few weeks to a couple of months.

Toddler Being Aggressive at Daycare
Aggressive behavior at daycare - hitting, biting, pushing, or grabbing - is very common in toddlers, particularly between ages 1-3. Toddlers are still developing impulse control, emotional regulation, and communication skills, and they often resort to physical behavior when they are frustrated, overwhelmed, tired, or unable to express their needs verbally. This does not mean your toddler is a "bad child" or that you are doing something wrong. Most toddler aggression decreases significantly as language skills improve and emotional regulation develops, typically between ages 3-4.

Bonding and Attachment Timeline for Adopted Babies
Bonding with an adopted baby is a real and achievable process, but it may follow a different timeline than biological bonding. Many adoptive parents feel a strong connection quickly, while for others it develops gradually over weeks or months. Consistent, responsive caregiving is the single most important factor in building secure attachment, regardless of how your family was formed.
Aggressive Play vs Normal Play
Rough-and-tumble play — wrestling, chasing, play-fighting, and superhero battles — is a normal and important part of child development, particularly for toddlers and preschoolers. It helps children develop physical coordination, social skills, self-regulation, and an understanding of boundaries. The key distinction between normal rough play and concerning aggression is whether both children are having fun, there is turn-taking in roles, and no one is intentionally trying to hurt the other.
My Toddler Is Aggressive Toward Pets
Toddlers being rough with pets is extremely common and almost never reflects true aggression or cruelty. Young children lack the motor control to be consistently gentle and do not yet understand that animals feel pain the way they do. With patient, consistent teaching about gentle touch and close supervision, most toddlers learn to interact safely with pets by age 3-4.
