Signs & concerns
What social milestones should a 3-year-old reach?
By age three, most children begin to play cooperatively with other children, show affection and empathy, take turns with reminders, and enjoy pretend play. These are flexible guideposts, not a checklist — a wide range is normal, and persistent concern deserves a relaxed developmental check.
Read the answer AnswerWhat social milestones should a 4-year-old reach?
Around 4, most children prefer playing with other kids, enjoy cooperative pretend play, take turns with reminders, comfort upset friends and want to please loved ones. These are flexible guides, not deadlines — a developmental check brings reassurance if your child shows little interest in others or no pretend play.
Read the answer AnswerWhat social milestones should a 5-year-old reach?
By age 5, most children prefer playing with other children, take turns and follow simple game rules, show empathy when a friend is upset, manage strong feelings better, and enjoy shared pretend play. Children vary widely; a friendly developmental check helps if your child seems markedly behind peers across several areas.
Read the answer AnswerWhat social milestones should a 6-to-9-month-old reach?
Between 6 and 9 months, most babies enjoy mirrors, respond to their name, share smiles and laughter, reach to be picked up, and start games like peek-a-boo, sometimes with early shyness around strangers. These are guides, not deadlines — a few weeks either way is normal.
Read the answer AnswerWhat social milestones should a 6-year-old reach?
Most six-year-olds enjoy cooperative play with friends, take turns in games with rules, share, want to please and be liked, and begin to understand fairness and others' feelings. Children develop at their own pace, so these are a guide, not a test — a gentle check helps if differences persist across home and school.
Read the answer AnswerWhat social milestones should a 9-to-12-month-old reach?
Between 9 and 12 months most babies respond to their name, play back-and-forth games like peek-a-boo, wave bye-bye, point to share interest, and look to your face for cues. Milestones are a guide, not a deadline. A friendly check is worth it if there's no babble, no gesture, no response to name by 12 months, or any loss of skills.
Read the answer AnswerWhat Social milestones should a frontline worker check during routine visits?
Frontline workers should check age-appropriate social milestones (ICF d7): shared smiles and name response in infancy, pointing and sharing by 12-18 months, pretend play and copying as a toddler, and turn-taking with peers by age 3. Persistent gaps or any loss of skills warrant a developmental check, not a wait-and-see approach.
Read the answer AnswerWhat social milestones should a newborn reach?
Newborns are social from birth — they calm to your voice and touch, gaze at faces, recognise your voice, and make eye contact during feeds. The first social smile usually appears around 6–8 weeks, with cooing and back-and-forth "chats" by 3 months. Wide variation is normal; mention to your doctor if there's no social smile by about 3 months.
Read the answer AnswerWhat social milestones should my 12-to-18-month-old have reached?
By 12–18 months, most toddlers point to share interest, follow your gaze, imitate everyday actions, enjoy give-and-take games like peekaboo, show affection, and seek you for comfort. These are guides, not deadlines. Mention it at your next visit if, by 18 months, your child rarely shares attention, doesn't point or respond to their name, or has lost an earlier skill.
Read the answer AnswerWhat Social milestones should my 18-to-24-month-old have reached?
By 18–24 months, most toddlers share interest by pointing and showing, copy everyday actions, begin simple pretend play, and seek a parent's reaction. Children vary widely; raise it at a routine visit if your toddler rarely points to share, shows little interest in copying, or has lost a social skill.
Read the answer AnswerWhat Social milestones should my 2-year-old have reached?
By around age 2, most toddlers copy others, show affection, get excited near other children, and begin simple pretend play — while still playing beside rather than with peers. Milestones are a guide, not a deadline, and a few still emerging is usually fine. Flag any lack of interest in others, no pretend play, or loss of skills with your paediatrician.
Read the answer AnswerWhat Social milestones should my 3-to-6-month-old have reached?
By 3 to 6 months most babies smile back, recognise familiar faces, enjoy watching people, laugh, and 'chat' in turn-taking coos. These are flexible guideposts, not a strict checklist. A gentle developmental check is wise if your baby isn't smiling back by 3 months or seems hard to engage by 6 months.
Read the answer AnswerWhat Social milestones should my 3-year-old have reached?
Around age 3, most children begin enjoying other children, taking simple turns, showing affection, comforting others, and engaging in pretend play. Social skills vary widely and are still emerging at this age — watch the overall pattern across home and playgroup, and seek a friendly developmental check if your child shows little interest in others, no pretend play, or has lost skills once present.
Read the answer AnswerWhat Social milestones should my 4-year-old have reached?
By 4, most children play cooperatively with friends, take turns and share, engage in imaginative role-play, show empathy when others are upset, follow simple group rules and talk about feelings. Skills emerge at different paces, so treat these as a guiding map — small gaps are common and respond well to play and a gentle developmental check.
Read the answer AnswerWhat Social milestones should my 5-year-old have reached?
By five, most children play cooperatively, take turns, share, follow simple game rules, and show empathy and a wish to please friends. These are typical patterns, not a strict checklist — and a gentle developmental check helps if your child finds joining in or reading others' feelings hard across home and school.
Read the answer AnswerWhat Social Milestones Should My 6-to-9-Month-Old Have Reached?
By 6 to 9 months most babies recognise familiar faces, smile and babble back, enjoy peek-a-boo, respond to their name and may show wariness of strangers — early signs of healthy social development. Every baby varies, so use this as a guide, not a deadline, and check in if social back-and-forth isn't emerging.
Read the answer AnswerWhat Social Milestones Should My 6-Year-Old Have Reached?
By six, most children play cooperatively, take turns, follow rules, form friendships and show empathy. Social skills vary widely — steady growth matters more than a perfect checklist, and persistent difficulty joining play across settings is worth a gentle check.
Read the answer AnswerWhat Social milestones should my 9-to-12-month-old have reached?
Between 9 and 12 months most babies respond to their name, play social games like peek-a-boo, share attention by following a point, use gestures such as waving, and show feelings by cuddling familiar people or being wary of strangers. These are gentle ranges, not strict deadlines.
Read the answer AnswerWhat Social milestones should my newborn have reached?
In the first three months, newborn social development is gentle: gazing at faces, calming to your voice, and a first social smile around 6–8 weeks. This is a watch-and-enjoy stage, not a checklist to pass — responsive, loving care is the foundation of all later social skill.
Read the answer AnswerSocial red flags prompting developmental referral
Refer when social-interaction red flags persist or cluster: limited eye contact, no social smile by ~3 months, absent joint attention and gesture (pointing/showing) by 12–15 months, no single words by 16 months, no two-word phrases by 24 months, or any loss of acquired social/language skills. These map to ICF d7 (interpersonal interactions); pair with a hearing check and refer without awaiting diagnostic certainty.
Read the answer AnswerWhen do children move from cooperative play to group games with rules?
Children typically move from cooperative play (around 3–4 years) to structured group games with rules between 5 and 7 years, as turn-taking, rule-following and handling winning or losing mature. A few months' variation is normal.
Read the answer AnswerWhen Do Children Move From Needing an Adult to Self-Soothing?
Children move from needing an adult to calm them (co-regulation) to self-soothing gradually: babies depend fully on a soothing adult, simple self-comfort emerges around 4–6 months, toddlers borrow your calm, and reliable self-soothing for everyday upsets grows across ages 3–5 and keeps maturing into the school years. Co-regulation is how self-regulation is learned.
Read the answer AnswerWhen do children move from playing alone to playing alongside others?
Children typically move from solitary play to parallel play (playing alongside others with similar toys) between 18 months and 3 years, becoming common around age 2. True cooperative, shared play usually emerges around 3–4 years. A gentle check is wise if there's no interest in other children by 2.5–3 years, especially with other delays.
Read the answer AnswerFrom parallel play to cooperative play: the timeline
Children typically move from parallel play (side-by-side) to cooperative play (sharing goals and rules) between about 3 and 5 years, with true cooperative play blossoming around 4–5. The stages overlap, individual variation is wide, and a child still enjoying parallel play at 3 is developing normally.
