What cognitive milestones should my 4-year-old have reached?
By four, most children count to ten, name colours, follow two- to three-step instructions, enjoy rich pretend play, and answer simple 'why' questions. These are guides, not a checklist — if several feel well behind, a gentle developmental check is the kind next step.
Read the answer AnswerWhat Cognitive milestones should my 5-year-old have reached?
By age five most children count to ten and beyond, name colours and shapes, follow three-step instructions, enjoy rich pretend play, and answer "why" questions. These are typical signposts within a normal range, not a fixed checklist — steady progress matters most, and a gentle developmental check helps if several are not yet emerging.
Read the answer AnswerWhat Cognitive milestones should my 6-to-9-month-old have reached?
Between 6 and 9 months most babies explore objects with purpose, repeat actions that cause an effect, begin searching for hidden toys (early object permanence), recognise familiar faces and pass objects hand to hand. There is a wide normal range; a developmental check helps if your baby isn't exploring, recognising faces or responding to sounds by 9 months.
Read the answer AnswerWhat Cognitive Milestones Should My 6-Year-Old Have Reached?
By six, most children count and recognise numbers, follow multi-step instructions, focus for about 15 minutes, sort and compare objects, and begin reading simple words. These ICF b1 cognitive milestones span a normal range, and timing varies widely from child to child.
Read the answer AnswerCognitive milestones for your 9-to-12-month-old
By 9–12 months most babies show object permanence (looking for hidden toys), cause-and-effect play, simple imitation like waving, and respond to their name. Pace varies widely — these are a gentle guide, not a test. A friendly developmental check is the right next step if anything feels off.
Read the answer AnswerWhat Cognitive milestones should my newborn have reached?
Newborns don't have a cognitive milestone checklist — early thinking shows as alertness: noticing faces, calming to your voice, brief tracking by 6–8 weeks and a first social smile around 6 weeks. Watch for never being alert, no startle to sound, or no fixing on faces by 2–3 months, and raise these with your paediatrician.
Read the answer AnswerWhat communication milestones should a 12-to-18-month-old reach?
By 12–18 months most toddlers say their first words (building to several by 18 months), point to show and request, follow simple one-step instructions, and use gestures like waving and head-shaking. Communication is the whole back-and-forth — looking, babbling, copying — not just words. Check in if there are no words, no pointing, no response to name, or any loss of skills by around 18 months.
Read the answer AnswerWhat communication milestones should a 18-to-24-month-old reach?
Between 18 and 24 months most toddlers grow to around 50 words, begin joining two words, follow simple one-step instructions, and point to share interest. Ranges are wide — but no words by 18 months or no two-word phrases by 24 months is worth a friendly developmental check.
Read the answer AnswerWhat communication milestones should a 2-year-old reach?
By age 2, most children use 50+ words, start joining two words together, follow simple instructions and point to named objects, with about half their speech understandable to familiar adults. Ranges vary widely; a check is worthwhile if there are very few words, no two-word combinations, no pointing to share, or any loss of skills.
Read the answer AnswerWhat communication milestones should a 3-to-6-month-old reach?
From 3 to 6 months most babies coo and make vowel sounds, smile and laugh back, turn towards voices, and enjoy back-and-forth 'chats' of squeals and early babble. These are gentle ranges, not a race. A relaxed check helps by 6 months if there are no sounds, no smiles, or no reaction to your voice.
Read the answer AnswerWhat communication milestones should a 3-year-old reach?
By age three, most children speak in three-word sentences, are understood by familiar people about 75% of the time, follow two-step instructions, and ask many questions. Milestones are a guide — a gentle check brings reassurance if a child isn't yet joining words, is very hard to understand, or has lost earlier skills.
Read the answer AnswerWhat communication milestones should a 4-year-old reach?
By age 4 most children speak in four-word-plus sentences, are understood by strangers most of the time, tell short stories, ask and answer questions, and enjoy back-and-forth conversation. Children develop at their own pace; a gentle check brings reassurance, not alarm.
Read the answer AnswerWhat communication milestones should a 5-year-old reach?
By five, most children speak in clear sentences understood by strangers, tell short stories in order, ask and answer why/how questions, and use near-adult grammar. They hold back-and-forth conversations and use language to imagine and joke. Children grow at their own pace, so check in if speech is unclear or sentences stay short or jumbled.
Read the answer AnswerWhat communication milestones should a 6-to-9-month-old reach?
Between 6 and 9 months, most babies babble with repeated sounds like "bababa", turn to their name, enjoy back-and-forth sound games, and use cries and gestures to communicate. Steady back-and-forth between you and your baby matters more than perfect words, and the whole picture matters more than any single milestone.
Read the answer AnswerWhat communication milestones should a 6-year-old reach?
By six, most children speak in clear full sentences strangers understand, hold a real back-and-forth conversation, tell a short story in order, follow two- to three-step instructions, and begin linking sounds to letters as reading starts. These are gentle guides — a check helps if speech is unclear, conversation is rare, or skills are lost.
Read the answer AnswerWhat communication milestones should a 9-to-12-month-old reach?
By 9–12 months, most babies babble varied sounds, respond to their name, understand "no", wave or point to share interest, and may say a first meaningful word around their birthday. These are guides, not deadlines — a friendly check helps if there's no babble, gesture or name response by 12 months.
Read the answer AnswerWhat communication milestones should a doctor check at routine visits?
At routine visits, check communication against age-anchored milestones — social signals and babble by 9–12 months, first words by 12–16 months, two-word combinations by 24 months, sentences by 36 months. Refer on no babble/gesture by 12 months, no words by 16 months, no two-word phrases by 24 months, or any loss of skills, with parallel audiology referral.
Read the answer AnswerWhat Communication milestones should a frontline worker check during routine visits?
On routine visits, frontline workers should check that a child listens and responds to sound, babbles, uses gestures, says first words by 16 months, and joins two words by 24 months. Act on any loss of skills or parental concern, refer for a hearing check in parallel, and route delays for a developmental assessment.
Read the answer AnswerWhat communication milestones should a newborn reach?
Newborns communicate before words — quietening to your voice, making eye contact, cooing by around 2 months, and a social smile by 6–8 weeks. These are wide, healthy ranges, not a test. Respond warmly and often; mention to your paediatrician any baby who never startles to sound, never watches faces, or by 3 months shows no cooing or smile.
Read the answer AnswerWhat Communication milestones should my 12-to-18-month-old have reached?
By 12–18 months most toddlers say their first words, point to share interest, follow simple one-step requests, and use gestures like waving. Understanding outpaces speech at this age. Consider a developmental check and hearing test if there are no words, no pointing, no response to name by 18 months, or any loss of skills.
Read the answer AnswerWhat Communication milestones should my 18-to-24-month-old have reached?
By 18–24 months most toddlers grow from about 20 words to 50+, start joining two words, follow simple instructions, and point to share interest. Communication has a wide normal range — steady progress matters most, and a clinician can guide you if words feel slow.
Read the answer AnswerWhat Communication milestones should my 2-year-old have reached?
By age 2, most children use 50+ words, begin joining two words together, follow simple instructions, and point to name familiar objects. They understand more than they can say. A gentle check is worth it if your child uses very few words, isn't combining words, or rarely gestures.
Read the answer AnswerCommunication milestones for your 3-to-6-month-old
By 3–6 months most babies coo, gurgle and laugh, smile back at you, turn towards voices and sounds, and take playful back-and-forth turns. Milestones are guides, not deadlines — but if your baby doesn't smile, make sounds or react to sound by 6 months, ask for a developmental and hearing check.
Read the answer AnswerWhat Communication milestones should my 3-year-old have reached?
By age three, most children speak in short three-word-plus sentences, follow two-step instructions, ask questions, and are understood by familiar adults much of the time. These are guideposts, not deadlines — every child grows at their own pace, and one missed step alone is rarely a worry.
