Keep modelling it (feed a doll, stir a pot) and watch over the coming weeks. If there's still no pretend or imitation by 18 months, a gentle developmental check is sensible.","q":"Is it normal if my toddler hasn't started pretend play at 14 months?"},{"a":"Not on its own. Object permanence firms up gradually across this age. Try slow hide-and-find games. Worry is only warranted if several cognitive skills together are well behind by 18 months.","q":"My 15-month-old doesn't always look for a dropped toy. Should I worry?"},{"a":"Repeat the same playful games — hiding toys, stacking, posting shapes, copying actions. Repetition is genuine learning at this age. Narrate what you do so words and ideas grow together.","q":"How can I support my toddler's thinking skills at home?"},{"a":"If by 18 months your toddler shows several lagging skills — no searching for hidden objects, no imitation, no use of objects for their purpose — book a developmental check.

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.","answer_md":"*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.*\n\n## In short\nBetween 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.\n\n## What to look for\nAround this age, many toddlers will:\n\n- **Find a hidden toy** — they look where you tucked it away, showing object permanence is firming up\n- **Explore with purpose** — banging, dropping, shaking and posting objects to see what happens\n- **Imitate you** — copying simple actions like stirring, brushing hair, or pretend-talking on a phone\n- **Use objects correctly** — drinking from a cup, holding a spoon, rolling a ball\n- **Follow a simple instruction** — \"give me the ball\" with a gesture\n- **Point to ask or to share** — showing they want you to notice something\n- **Begin simple pretend** — feeding a doll, pushing a toy car\n\n## The science\nCognitive 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.\n\n## The Pinnacle way\nEvery 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).\n\n## Trusted sources\nGuided by the WHO ICF framework for mental functions (b1) and CDC developmental-milestone guidance for toddlers.\n\n**Next step —** if a few of these skills seem far behind by 18 months, book a friendly developmental check with the Pinnacle team on WhatsApp: +91 91001 81181.\n\nThis is general information, not a diagnosis — individual assessment and diagnosis require an appropriately qualified healthcare professional.","canonical":"https://pinnacleblooms.org/ask/what-cognitive-milestones-should-my-12-to-18-month-old-have-reached","editorial":{"reviewed_at":"2026-06-11T20:12:18.613642+00:00","reviewed_by":null,"developed_by":"SETU
