Object permanence — knowing things exist when out of sight — usually emerges between 8 and 12 months and is established by around 12 months. In class, expect babies and toddlers to enjoy peekaboo and search for hidden or dropped toys. It's a normal milestone to observe, not test; flag any child well past 12 months who never searches for hidden objects.

*When a hidden toy is no longer a vanished toy — that quiet moment of searching is one of the earliest signs a child's thinking is building.*

## In short
[Object permanence](/object-permanence) — the understanding that things continue to exist even when out of sight — typically emerges between **8 and 12 months**, and is usually well established by around 12 months. In a classroom, expect babies and toddlers to look for hidden objects, enjoy peekaboo, and search for a dropped or covered toy. This is a normal milestone, not something to test or grade.

## What a teacher can expect
From around **8 months**, a child begins to search briefly for a partly hidden object. By **10–12 months**, most will uncover a fully hidden toy and delight in games where you hide and reveal. By the toddler years this matures into looking in the *last* place something was hidden and, later, holding an idea of a person or object in mind even when absent.

In class you may notice:
- Joy and anticipation in peekaboo and hide-the-toy games
- Searching under a cloth or behind a container for a hidden object
- Settling more easily as they grasp that a parent who leaves still exists and returns
- Following a dropped toy with their eyes and reaching for it

These are foundations for memory, problem-solving and later separation comfort. Every child's timing varies a little, and bilingual or quieter children are no exception.

## When to flag
If a child well past 12 months shows no interest in hidden-object play, never searches for a covered toy, or this sits alongside delays in eye contact, gesture or response to name, share your observation with the family and suggest a general developmental check rather than waiting.

## 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 classroom observation alone. Our [early-intervention](/early-intervention) team partners with educators to turn a teacher's notes into a clear, supportive next step.

## Trusted sources
Aligned with CDC "Learn the Signs. Act Early." developmental milestones, the American Academy of Pediatrics, and WHO ICF activity and participation domains.

**Next step —** noticed a child past their first birthday who never searches for hidden things? Share your observation with the family and reach the Pinnacle team on WhatsApp +91 91001 81181 for a friendly developmental check.

This is general information, not a diagnosis — individual assessment and diagnosis require an appropriately qualified healthcare professional.
