# At what age should a child develop object permanence?

Object permanence — understanding that things exist even when out of sight — emerges around 8 months and is usually well established by 12–18 months. Most babies find a fully hidden toy by their first birthday and love peek-a-boo. A gentle developmental check is worthwhile if there's no interest in finding hidden objects by 15–18 months.

*That moment your baby hunts for a toy you've hidden under a cloth — that's a quiet milestone of thinking, not just play.*

## In short
Object permanence — knowing that things still exist even when they're out of sight — begins to emerge around **8 months** and is usually well established by **12–18 months**. Most toddlers can find a fully hidden object by their first birthday, and enjoy peek-a-boo and hide-and-find games soon after. It's a normal, gradual unfolding, so a few weeks either way is perfectly typical.

## How it unfolds
- **6–8 months** — your baby starts to look for a partly hidden toy, or for one they just dropped.
- **8–12 months** — they search for a fully hidden object, and love peek-a-boo because they now *expect* your face to return.
- **12–18 months** — they remember where something was hidden even after a short delay, and may search in more than one place.

Object permanence is a foundation for memory, problem-solving and later language — it's how a child learns that words and people are real even when not in view.

## The science
This skill reflects developing working memory and the understanding that the world is stable and predictable. It's why a baby who once forgot a hidden toy will, months later, lift the cloth with confidence.

## When to gently check in
If by around **15–18 months** your toddler shows no interest in finding hidden objects, doesn't enjoy peek-a-boo style games, or this sits alongside other concerns about play, gestures or words, a friendly developmental check is worthwhile — early and reassuring, never alarming.

## The Pinnacle way
A clinical [AbilityScore®](/ask/what-is-the-abilityscore-and-how-is-it-calculated) and any diagnosis are formed only at a Pinnacle Blooms Network centre under qualified clinician care — never from a web page. We can map your child's [cognitive and play milestones](/object-permanence) and, where helpful, support them through [occupational therapy](https://www.pinnacleblooms.org/best-occupational-therapy-center-india-proven-improvement-rate).
