object permanence
What it means if your child isn't yet showing object permanence
Object permanence is a child's understanding that things still exist when out of sight, usually emerging between 8 and 12 months and strengthening through the toddler years. If your toddler isn't yet showing it clearly, in most cases it is simply still developing — not a diagnosis. Watch play and peek-a-boo games, note any loss of skills, and arrange a friendly developmental check if you have other worries, because early support works best.
Watching your little one search for a toy that's slipped under a blanket — and noticing they don't yet — is exactly the kind of gentle attention that helps a child thrive.
In short
Object permanence is your child's growing understanding that things still exist even when they can't be seen, heard or touched. It usually blossoms between about 8 and 12 months and keeps strengthening through the toddler years. If your toddler isn't yet clearly showing it, in most cases this simply means it is still developing — children arrive at this milestone on slightly different timelines. It is not a diagnosis. It is, however, a useful prompt to observe play and, if you have other worries, to arrange a friendly developmental check.What this looks like — and what to watch
A child who has grasped object permanence will look for a toy you hide under a cloth, enjoy peek-a-boo, search where they last saw something, and may protest when you step out of the room (that's healthy attachment, not a problem).Gentle flags worth a clinician's eye between 12 and 36 months:
- Not searching at all for a hidden or dropped object well past their first birthday.
- Little interest in peek-a-boo, hide-and-seek or simple search games.
- Not yet looking for you or a favourite toy when it disappears.
- Any loss of a skill they clearly had before — this always deserves prompt review.
Remember: object permanence rarely sits alone. Clinicians look at it alongside play, attention, communication and motor skills to see the whole, wonderful picture of your child.
The science
Object permanence is a cornerstone of early thinking (cognition) — it underpins memory, problem-solving and later language, because words themselves stand for things that aren't present. It develops through everyday play and warm, responsive interaction, which is why simple games matter so much.The Pinnacle way

What to watch
Between 12 and 36 months, seek a developmental check if your child does not search at all for a hidden or dropped object, shows little interest in peek-a-boo or search games, doesn't look for you or a favourite toy when it disappears — or loses a skill they once had.
Try this at home
Play peek-a-boo and gentle 'where did it go?' games daily — partly hide a favourite toy under a cloth and cheer when your child finds it. These simple, joyful games are exactly how object permanence grows.

Frequently asked
At what age should my child show object permanence?
It usually begins between about 8 and 12 months and keeps strengthening through the toddler years. Children arrive at this milestone on slightly different timelines, so a little variation is normal.
Is a delay in object permanence a sign of something serious?
Not on its own. It is one part of early thinking, and clinicians look at it alongside play, attention, communication and motor skills. If you have several worries or notice a loss of skills, a developmental check is wise.
How can I help my child develop object permanence?
Play peek-a-boo, hide-and-seek with toys, and partly cover a favourite object so your child searches for it. Warm, responsive, repeated play is exactly how this skill grows.
