YOUR QUESTION. A CLEARER NEXT STEP.
Signs Your Toddler May Need Support with Object Permanence
Between 12 and 36 months, signs your toddler may need support with object permanence include not searching for a hidden toy, little interest in peek-a-boo, not noticing when a favourite item is moved or gone, or no sense that a parent still exists during separation. These are signs to observe through play, not to diagnose at home — many toddlers vary in pace. Concern grows when a pattern persists across months or appears alongside delays in memory, play or communication. A gentle developmental screen is the kindest next step.

Peek-a-boo isn't just a game — it's how little ones learn that what disappears still exists, and that you always come back.
In short
Object permanence is your child's growing understanding that things — and people — still exist even when out of sight. Between about 12 and 36 months, signs worth a gentle look include not searching for a hidden toy, little interest in peek-a-boo, not noticing when a favourite item is moved or gone, or unusually intense distress at every separation with no sense that you'll return. These are signs to observe and explore through play, not to diagnose at home — many toddlers simply move at their own pace.
Signs to watch (12–36 months)
Searching and memory
- Doesn't look for a toy you've hidden under a cloth or behind your hands
- Quickly "forgets" a toy the moment it's out of view, well past the first year
- Little reaction when a familiar object suddenly isn't where it usually is
Play and social games
- Limited delight or curiosity in peek-a-boo or hide-and-find games
- Doesn't lift cups or flaps to find something tucked underneath
- By 18–24 months, doesn't seem to hold a parent "in mind" — neither soothed by knowing you'll return nor reassured when you reappear
What shifts this from ordinary variation towards something to assess is a pattern that persists across several months, delays in more than one area (such as play, memory and communication together), or worries you've also noticed in attention or understanding.
The gentle science
Object permanence is a cognitive milestone — a foundation for memory, problem-solving and confident separation. It usually strengthens steadily through the toddler years, often shown when a child searches for a hidden object or enjoys finding what's been tucked away. Rich, repeated play — hiding, finding, naming — is exactly how this skill grows.

CONNECT THE ANSWER TO YOUR CHILD’S DAY
Something to notice. Something to discuss.
What to notice
Not searching for hidden toys, little interest in peek-a-boo, not noticing when a favourite object is moved or gone, and no sense that a parent still exists during brief separations — especially when a pattern persists across several months.
In everyday life
Play simple hide-and-find games daily: hide a favourite toy under a cloth while your child watches, then cheer when they find it. Repetition gently builds the 'it still exists' understanding.

Bring your questions to a first visitQuestions families ask
At what age should object permanence develop?
It usually begins in the first year and strengthens steadily through the toddler years (about 12–36 months), shown when a child searches for a hidden toy or enjoys peek-a-boo. Children vary, so a persistent pattern matters more than any single moment.
Is not playing peek-a-boo a sign of a problem?
Not on its own. Many toddlers simply prefer other play. It becomes worth a gentle look only when limited interest sits alongside other signs — such as not searching for hidden objects or delays in memory and communication — over several months.
Can I help build object permanence at home?
Yes. Hide-and-find games, peek-a-boo, and naming objects as they appear and disappear all help. Warm, repeated play is exactly how this skill grows. If you remain unsure, a developmental screen can guide you.
