object permanence
Is it normal my toddler isn't showing object permanence yet?
Object permanence usually begins around 8 months and is well established by 12–24 months, so most toddlers already show it. If your child isn't looking for hidden or dropped objects by around 12–15 months, a gentle developmental check is wise — not a diagnosis, just early observation alongside vision, hearing, play and communication.
If you're peeking at your toddler hunting for a hidden toy and wondering whether they should already "get it," that watchful love is exactly what helps them thrive.
In short
Object permanence — knowing a toy still exists even when it's out of sight — typically begins around 8 months and is usually well established between 12 and 24 months. So for most toddlers, this skill should already be emerging or present. If your child shows no sign of looking for hidden or dropped objects by around 12–15 months, it's worth a gentle developmental check — not because anything is wrong, but because early observation turns small questions into early opportunities.What to watch in the toddler years
Object permanence rarely stands alone — it grows alongside attention, memory, play and communication. Reassuring signs you may already see:- Searching — looking for a toy you hide under a cloth, or peering after something that rolls away.
- Peekaboo delight — anticipating your face returning, because they know you're still there.
- Person permanence — protesting briefly when you leave, then settling — a healthy sign they remember you.
Gentle flags worth a clinician's eye: little interest in finding hidden objects by ~15 months, very limited eye contact or shared play, not following your point or gaze, or any loss of a skill once shown. Remember that play needs both seeing and hearing well — so vision and hearing checks matter too.
The science
This skill marks an early leap in working memory and mental representation — your toddler is building an inner picture of the world. It is one thread in cognitive development (ICF d1), best understood within the whole pattern of how your child plays, communicates and connects, never from a single test.The Pinnacle way
A clinical AbilityScore® and any diagnosis are formed only at a Pinnacle Blooms Network centre, under qualified clinician care — never from an online list. Our clinicians build your child's own developmental baseline and shape playful support around strengths.

What to watch
By around 12–15 months, seek a check if your toddler shows no interest in finding hidden or dropped toys, little eye contact or shared play, doesn't follow your point or gaze, or has lost a skill once shown. Vision and hearing checks matter too.
Try this at home
Play hide-and-seek with a favourite toy under a cloth, or roll a ball behind a cushion and wait. Each time your toddler searches, they're flexing memory — narrate it warmly: 'Where did it go? There it is!'

Frequently asked
At what age should my toddler have object permanence?
It usually begins around 8 months and is well established between 12 and 24 months. If your toddler isn't searching for hidden or dropped objects by around 12–15 months, a gentle developmental check is sensible — it's observation, not diagnosis.
How can I tell if my toddler understands object permanence?
Look for searching when you hide a toy under a cloth, delight in peekaboo as they anticipate your face, and a brief protest when you leave the room. These show they hold an inner picture of things and people that are out of sight.
Should I worry if object permanence seems delayed?
Not by itself — but it's worth a clinician's eye if it appears alongside little eye contact, limited shared play, not following your point, or any loss of a skill once shown. Hearing and vision should also be checked, as play needs both.
