YOUR QUESTION. A CLEARER NEXT STEP.
If a child isn't yet showing object permanence
Object permanence — knowing a hidden object or person still exists — usually emerges between about 4 and 8 months and is clearly visible by 8–12 months. A baby not yet searching for hidden toys or enjoying peek-a-boo is very often simply on their own timeline. Keep playing hide-and-find games, keep watching, and arrange a calm developmental check if the skill is well behind alongside other delays — early support works best.

Peek-a-boo isn't just play — it's how a baby learns that you still exist when you step out of view, and noticing this is thoughtful, loving care.
In short
Object permanence — knowing a hidden object or person still exists — usually emerges gradually between about 4 and 8 months, and is often clearly visible by 8–12 months. If a baby in your care is not yet searching for a hidden toy or enjoying peek-a-boo, this is very often simply where they are on their own timeline. Keep playing, keep watching, and if the skill seems well behind alongside other delays, a calm developmental check is wise — not because anything is wrong, but because early support works beautifully.
What to watch
Object permanence builds in small steps, so look at the whole picture rather than one milestone:
- Around 4–6 months — a baby may glance toward where a toy vanished or wait for a face to reappear in peek-a-boo.
- Around 8–12 months — most babies actively search for a toy hidden under a cloth and clearly enjoy peek-a-boo and hide-and-find games.
- Gentle flags — if by around 12 months there's no searching and little eye contact, few sounds or babbles, limited interest in faces, or delays in sitting and reaching, a clinician's look is worthwhile.
The aim is not alarm — it's turning a small question into an early opportunity.
The science
Object permanence reflects growing memory and attention — the brain holding an idea of something it can no longer see. It's nurtured through everyday play: hiding and finding toys, peek-a-boo, and naming people as they come and go. Rich, responsive play is the most powerful support you can offer at this age.
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 watch how your little one plays, attends and remembers, and shape gentle support around it.

CONNECT THE ANSWER TO YOUR CHILD’S DAY
Something to notice. Something to discuss.
What to notice
Watch the whole picture: by around 12 months most babies search for a toy hidden under a cloth and enjoy peek-a-boo. A gentle flag is no searching by 12 months alongside little eye contact, few babbles, limited interest in faces, or delays in sitting and reaching. These are reasons for a calm developmental check, not a diagnosis.
In everyday life
Play simple hide-and-find games daily — slowly cover a favourite toy with a cloth while your baby watches, then encourage them to lift it. Lots of slow, smiling peek-a-boo helps too. Keep it joyful and unhurried.

Bring your questions to a first visitQuestions families ask
At what age should object permanence appear?
It builds gradually — many babies begin around 4–6 months and most clearly search for hidden toys and enjoy peek-a-boo by 8–12 months. Each baby has their own timeline.
How can I help develop object permanence?
Play hide-and-find games and peek-a-boo, slowly covering a toy while your baby watches and encouraging them to find it. Name people as they come and go. Responsive, playful interaction is the strongest support.
When should I arrange a check?
If by around 12 months there's no searching for hidden objects alongside other signs — little eye contact, few babbles, limited interest in faces, or motor delays — a calm developmental check is wise. This is to open early support, not a diagnosis.
