object permanence
Object permanence: when it develops and what teachers can expect
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 — 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

What to watch
Flag for a developmental check if a child well past 12 months shows no interest in peekaboo and never searches for a hidden or covered toy, especially alongside weak eye contact, gesture or response to name.
Try this at home
Play simple hide-and-reveal games — cover a favourite toy with a cloth and let the child uncover it. Their delighted searching shows object permanence in action and builds memory and confidence.
