Cognitive
Cognitive milestones for your 18-to-24-month-old
Between 18 and 24 months most toddlers begin pretend play, follow one-step instructions, point to name pictures or body parts, and solve simple problems by trial and error. These are guides, not deadlines — a single missing skill is rarely a worry, but persistent gaps deserve a friendly developmental check.
The leaps your toddler makes between 18 and 24 months are quiet but extraordinary — every game of pretend is a brain at work.
In short
Between 18 and 24 months, most toddlers begin pretend play, follow simple one-step instructions, point to name body parts or pictures, and explore how things work through trial and error. These are guides, not deadlines — children bloom along their own timeline, and a single missing skill is rarely cause for worry.What you may see emerging
Thinking and problem-solving- Tries different ways to reach a toy, fit a shape or open a container
- Finds an object you hide under a cloth (object permanence)
- Begins simple pretend play — feeding a doll, "talking" on a toy phone
Understanding and attention
- Follows simple instructions like "Give me the ball"
- Points to familiar pictures or body parts when named
- Recognises and explores how everyday objects are used
Memory and curiosity
- Imitates household actions (sweeping, stirring) hours after seeing them
- Sorts or matches a few familiar objects by the end of this period
The science
The WHO ICF groups these as mental functions (b1) — the foundations of attention, memory, and reasoning. They grow through warm, everyday interaction: naming what you see, giving little choices, and letting your child puzzle things out with gentle help.The Pinnacle way
A clinical AbilityScore® and any diagnosis are formed only at a Pinnacle Blooms Network centre, under qualified clinician care — never from an online list. If something feels off, a friendly developmental check across the cognitive domain or special education support can offer clarity and reassurance.Trusted sources

What to watch
Gently note if, by 24 months, your toddler shows no pretend play, doesn't follow any simple instruction, or seems to lose skills they once had — these are worth mentioning at a developmental check rather than waiting.
Try this at home
Turn daily chores into thinking games: hand your toddler a cloth to 'help' wipe, hide a favourite toy under a cup for them to find, or pause a familiar routine and let them show you what comes next.

Frequently asked
Is it normal if my 20-month-old doesn't pretend play yet?
Pretend play often blooms across this whole window, so a 20-month-old just starting is well within range. Encourage it by modelling — feed a teddy, 'drive' a toy car — and if there's still no pretend play by 24 months, mention it at a developmental check.
My toddler understands me but says few words — is their thinking okay?
Understanding language well is itself a strong cognitive sign. Comprehension often runs ahead of speech at this age. If you're concerned about words specifically, a speech and language check can offer reassurance alongside a look at overall development.
When should I seek a developmental check?
Consider a check if, by 24 months, your toddler shows no pretend play, follows no simple instructions, doesn't point to share interest, or appears to lose previously gained skills. Persistent parental worry alone is also a good enough reason to ask.
