Quick Answer
Separation anxiety is common in infancy and early childhood and often becomes especially noticeable during the second half of the first year and the toddler years.
A child may cry, cling to a parent, resist daycare or preschool, become upset when a parent leaves the room, or have trouble settling at bedtime.
Parents can usually help by creating short, predictable goodbyes, maintaining consistent routines, practicing brief separations, and calmly reassuring children that they will return.
Key Takeaways
- Separation anxiety is often a normal developmental stage.
- It commonly appears during infancy and toddlerhood.
- Daycare, preschool, travel, illness, new caregivers, and family changes can temporarily increase clinginess.
- Keep goodbyes warm, confident, predictable, and relatively brief.
- Tell your child you are leaving rather than secretly disappearing.
- Return when you said you would whenever possible.
- Practice brief separations with trusted caregivers.
- Praise your child for coping, even if the separation was difficult.
- Persistent anxiety that interferes with school, sleep, activities, or everyday functioning deserves medical attention.
Why Separation Anxiety Happens
You arrive at daycare. Your child realizes you are about to leave. Suddenly they are wrapped around your leg and the tears begin.
Separation anxiety can be emotionally difficult because your child’s distress feels so personal.
But a child becoming upset when you leave does not necessarily mean something is wrong.
Often, it reflects an important developmental change: your child understands that you can leave, but does not yet have an adult understanding of time or complete confidence that you will return.
Dr. G’s Pearl
The goal is not to make sure your child never cries when you leave. The goal is to help your child gradually learn: “My parent leaves, I am safe, and my parent comes back.”
What Separation Anxiety Looks Like at Different Ages
Babies
As babies become more aware of familiar and unfamiliar people, they may become upset when a parent leaves the room or when someone unfamiliar approaches.
Toddlers
Toddlers have strong preferences and powerful emotions, but a limited understanding of time. “I’ll be back after lunch” does not feel the same to a 2-year-old as it does to an older child.
Preschoolers
Preschoolers may struggle with school drop-off, daycare, babysitters, bedtime, travel, or unfamiliar environments.
School-Aged Children
Occasional separation worries can still occur, especially during transitions or stressful periods. Persistent fear that prevents school attendance, activities, or normal functioning deserves closer attention.
Common Triggers
- starting daycare or preschool
- a new caregiver
- moving or traveling
- illness
- a new sibling
- a parent returning to work
- changes in family routine
Temperament also matters. Some children naturally take longer to warm up to unfamiliar people, places, and situations.
Common Signs of Separation Anxiety
- crying when a parent leaves
- clinging tightly to a parent
- following a parent from room to room
- resisting daycare or preschool drop-off
- becoming upset with a babysitter
- having difficulty falling asleep without a parent nearby
- waking and calling for a parent at night
- repeatedly asking when a parent will return
- complaining of stomachaches or headaches before separation
How Parents Can Help
1. Create a Predictable Goodbye
Use a simple ritual that stays roughly the same.
Hug. Kiss. “I love you. I’ll be back after snack.” Goodbye.
2. Keep Goodbyes Relatively Short
Long emotional departures can make the separation feel even bigger. Be loving and reassuring, but also confident.
3. Do Not Sneak Away
Slipping out while your child is distracted may prevent crying in that moment, but it can make future separations less predictable.
Tell your child you are leaving. Predictability helps build trust.
4. Explain Your Return in Child-Friendly Language
Young children do not understand clock time very well.
Instead of “I’ll be back at 2:30,” try “I’ll be back after your nap.”
5. Practice Short Separations
When possible, start with brief periods away from your child with a familiar caregiver. Return when you said you would.
6. Stay Calm and Confident
Children watch facial expressions, tone of voice, and body language closely.
You can acknowledge your child’s feelings without communicating that the situation is unsafe:
“I know you don’t want me to leave. You’re safe with Grandma. I’ll come back.”
7. Praise Coping
After the separation, focus on what your child managed to do:
“You missed me, and you stayed with Grandma while I went to the store.”
Daycare and Preschool Drop-Off
Drop-off can be one of the hardest times for both parent and child.
- Hang up the backpack.
- Help your child choose an activity.
- Give one hug and one kiss.
- Say when you will return in language your child understands.
- Say goodbye.
- Leave.
Many children who cry intensely at the door become engaged in play shortly afterward.
Try Not to Keep Coming Back After Goodbye
Walking back into the room because your child is crying can restart the entire separation process.
There are exceptions—for example, if staff tell you your child is ill or genuinely needs you—but routine separation distress is usually helped by consistency.
Separation Anxiety at Bedtime
Separation anxiety often appears at bedtime because bedtime itself is a separation.
A child may ask for repeated hugs, call a parent back into the room, cry when the parent leaves, or wake overnight looking for a parent.
A calm and predictable bedtime routine can help.

A Simple Plan Parents Can Try
- Choose a simple goodbye ritual.
- Tell your child when you are leaving.
- Explain when you will return using language your child understands.
- Keep the goodbye warm but brief.
- Leave confidently.
- Return when promised whenever possible.
- Practice short separations with trusted caregivers.
- Praise your child afterward for coping.
What Not to Do
Do Not Shame the Child
Avoid comments such as “Big kids don’t cry.” The emotion is real even when the situation is safe.
Do Not Make the Goodbye Dramatic
Repeatedly asking whether your child will be okay can accidentally communicate that there is something to fear.
Do Not Sneak Out Routinely
Children benefit from learning that departures are predictable.
Do Not Cancel Every Separation
If every protest immediately ends the separation, the child has fewer opportunities to learn that they can cope safely without the parent for short periods.
When Separation Anxiety Affects School Attendance
School refusal deserves more attention than ordinary drop-off tears.
A child may complain of stomachaches, headaches, nausea, dizziness, or feeling too sick to attend school. These symptoms may be genuine physical expressions of anxiety.
If separation fears repeatedly prevent school attendance or cause major impairment, contact your pediatrician.
When Does Normal Separation Anxiety Become More Concerning?
Normal separation anxiety usually improves as children mature and gain confidence.
Anxiety deserves closer evaluation when the intensity is out of proportion to the situation or when it begins interfering substantially with everyday life.
- repeated refusal to attend school or daycare
- inability to participate in age-appropriate activities
- extreme distress whenever a parent leaves
- persistent fear that something terrible will happen to a parent
- persistent refusal to sleep without a parent
- frequent physical complaints associated with separation
- significant disruption of family functioning
When to Call Your Pediatrician
Talk with your pediatrician if your child’s separation anxiety:
- seems unusually intense for their developmental stage
- is becoming progressively worse
- continues for an extended period without improvement
- prevents regular daycare or school attendance
- interferes significantly with sleep
- prevents participation in age-appropriate activities
- causes frequent headaches, stomachaches, or other physical complaints
- causes major distress throughout the family
- occurs along with developmental, behavioral, or emotional concerns
When to Seek Urgent Help
Ordinary separation anxiety is not a medical emergency.
Seek urgent professional help if a child’s behavior creates an immediate safety concern or if there are serious symptoms unrelated to ordinary separation distress.
Call 911 or seek emergency care if there is an immediate risk of serious harm.
Dr. G’s Pearl
A calm goodbye does not mean you are ignoring your child’s feelings. You can be loving and reassuring while still showing confidence that your child can handle the separation.
Frequently Asked Questions
At what age does separation anxiety usually start?
It often becomes noticeable during the second half of the first year and may continue through the toddler and preschool years.
Does crying at daycare mean my child is not ready?
Not necessarily. Many children cry during drop-off and settle shortly after the parent leaves.
Should I sneak away if my child cries when I leave?
Usually no. Predictable goodbyes help children learn that parents leave and return.
Should I go back if my child is crying?
Usually not simply because of ordinary separation protest. Repeatedly returning can restart the goodbye. Of course, return if the caregiver tells you your child genuinely needs you.
Can separation anxiety return after it has improved?
Yes. Illness, travel, moving, a new sibling, a new school, changes in childcare, or other transitions can temporarily bring it back.
Can separation anxiety affect sleep?
Yes. Younger children may resist bedtime, wake looking for a parent, or have difficulty settling alone during periods of increased separation anxiety.
The Bottom Line
Separation anxiety is a normal part of development for many babies, toddlers, and preschoolers.
Help your child by making separations predictable: say goodbye, keep the routine short, explain when you will return in language your child understands, and come back when promised whenever possible.
If the anxiety becomes severe, persistent, or begins interfering with school, sleep, activities, or normal family life, talk with your pediatrician.
