# Cognitive milestones for your 12-to-18-month-old

Between 12 and 18 months most toddlers begin finding hidden toys, imitating everyday actions, using objects correctly, following simple instructions and starting basic pretend play. These are emerging skills that grow week by week — a band of typical progress, not a strict checklist. If several lag by 18 months, a gentle developmental check is wise.

*The way your toddler hunts for a hidden toy, copies your stir of a spoon, or pushes a button to make something happen — that's their thinking mind blossoming.*

## In short
Between 12 and 18 months, most toddlers begin to solve simple problems, look for hidden objects, imitate everyday actions, and use objects the way they're meant to be used. These are emerging skills that grow week by week, so think of them as a band of typical progress rather than a strict checklist. If several are well behind by 18 months, a gentle developmental check is wise.

## What to look for
Around this age, many toddlers will:

- **Find a hidden toy** — they look where you tucked it away, showing object permanence is firming up
- **Explore with purpose** — banging, dropping, shaking and posting objects to see what happens
- **Imitate you** — copying simple actions like stirring, brushing hair, or pretend-talking on a phone
- **Use objects correctly** — drinking from a cup, holding a spoon, rolling a ball
- **Follow a simple instruction** — "give me the ball" with a gesture
- **Point to ask or to share** — showing they want you to notice something
- **Begin simple pretend** — feeding a doll, pushing a toy car

## The science
Cognitive skills sit within ICF *mental functions (b1)* — the foundations of memory, attention and problem-solving. They grow through play and repetition, so the same game offered again and again is real learning, not boredom.

## The Pinnacle way
Every child's pace is their own, and a single skill arriving late is rarely a worry. AbilityScore® is part of Pinnacle’s developmental assessment. Diagnosis, where needed, requires an appropriately qualified healthcare professional. Explore [cognitive development](/cognitive), how we support learning through [special education](/special-education), and [how the AbilityScore® is calculated](/ask/what-is-the-abilityscore-and-how-is-it-calculated).

## Trusted sources
Guided by the WHO ICF framework for mental functions (b1) and CDC developmental-milestone guidance for toddlers.

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