TL;DR:

  • Milestone lists guide observation and promote conversations with health visitors rather than assigning pass/fail judgments.
  • Contact your health visitor immediately if you notice regression, absent key behaviors, or signs of developmental concerns.

This is a concise, age-ordered list of milestones covering newborn to five years across four domains: communication and language, social and emotional, movement and physical, and cognition, fine motor skills, and self-help. If you are worried about your child’s development at any point, contact your health visitor or GP. You do not need to wait for a scheduled review.

Quick summary: UK routine development reviews

  • 1–2 weeks: newborn check, feeding, weight, and general health
  • 6–8 weeks: GP physical check plus health visitor review of feeding, sleep, and early social responses
  • 9–12 months: health visitor review; ASQ-3 questionnaire often sent in advance
  • 2–2.5 years: health visitor review; second ASQ-3 questionnaire typically sent beforehand

The ASQ-3 (Ages and Stages Questionnaire, Third Edition) is a parent-completed screening tool your health visiting team uses to structure these reviews. You fill it in at home and bring it along. It covers the same four domains as this checklist.

One red flag to act on now, without waiting: if your child loses a skill they had before, that is called regression. Regression requires urgent medical advice — call your GP the same day, not at the next scheduled review.

Pro Tip: Write two or three observations in your child’s Red Book before every review. Health visitors genuinely welcome a short, specific note: “stopped pointing at 11 months” or “no longer making eye contact at mealtimes.” A 30-second video clip on your phone is even better.

What does the full list of milestones look like from newborn to five years?

Healthier Together organises milestones by age band and domain. The table below draws on that framework. Treat every entry as a guide, not a deadline. Neurodivergent children often follow uneven profiles, and developmental variation is normal — what matters is the overall direction of travel, not hitting each box on a specific date.

Age Communication & language Social & emotional Movement & physical Cognition, fine motor & self-help Red flag Who to contact
Newborn Startles to sound; quiets to familiar voice Brief eye contact; calms when held Moves all four limbs; strong grasp reflex Tracks a face briefly at close range No response to sound or light Midwife / health visitor
2 months Coos and makes soft vowel sounds Social smile emerging; watches faces Lifts head briefly when on tummy Follows a moving object with eyes No social smile; no response to voices Health visitor
4 months Babbles; laughs; turns toward sounds Smiles spontaneously; enjoys interaction Holds head steady; rolls tummy to back Reaches for objects; brings hands to mouth No babble; not reaching for objects Health visitor
6 months Responds to own name; babbles consonants Recognises familiar faces; shows stranger anxiety beginning Sits with support; bears weight on legs Passes objects hand to hand; mouths toys No babble; not sitting with support Health visitor
9 months Uses gestures (waving, pointing beginning); imitates sounds Separation anxiety; plays peek-a-boo Pulls to stand; crawls or bottom-shuffles Picks up small objects with pincer grip developing No babble; no gestures; not bearing weight Health visitor / GP
12 months Says one or two words with meaning; points to request Plays alongside others; shows objects to adults Stands alone briefly; may take first steps Drinks from a cup with help; stacks two blocks No words; no pointing; not standing Health visitor / GP
18 months Uses a small number of words; names familiar objects Parallel play; shows affection; has tantrums Walks independently; climbs stairs with help Feeds self with spoon; scribbles Fewer than six words; not walking GP; ask about SALT referral
2 years Phrases with a couple of words; follows simple two-step instructions Plays near other children; begins to show empathy Is physically active with running, kicking a ball, and jumping Turns pages; removes shoes; beginning toilet awareness No two-word phrases; not running GP; SALT referral
3 years Sentences of a few words; begins asking questions like “why?” Takes turns; plays with others; expresses feelings Pedals a tricycle; climbs confidently Dresses with help; uses a fork; washes hands Speech mostly unclear to strangers; not playing with others GP / community paediatrics
4 years Tells simple stories; uses past tense Cooperates in group play; shows empathy Can hop on one foot and catch a ball Buttons clothing; draws a person with four parts Cannot follow three-step instructions GP / community paediatrics
5 years Uses full sentences; can retell a story in sequence Negotiates with peers; manages some frustration Performs skipping and can balance on one foot for several seconds Writes own name; dresses independently; uses toilet alone Cannot be understood by unfamiliar adults GP; school SENCO referral

Pro Tip: If your child is neurodivergent, their profile will likely be uneven — strong in one domain, slower in another. That is not failure. It is a profile. Bring the whole picture to your health visitor, not just the gaps.

What do the four milestone domains actually mean?

Most parents encounter the word “domains” in a health visiting leaflet and glaze over. Here is what each one means in plain terms, and one or two things you can do in an ordinary day to support it.

Communication and language

This covers everything from a newborn’s first coo to a five-year-old retelling a story. It includes understanding language (receptive) as well as using it (expressive). Crucially, it also includes non-verbal communication: gestures, pointing, eye contact, and for some children, AAC (augmentative and alternative communication) devices or PECS (Picture Exchange Communication System).

Hands holding child communication card in playroom

The NHS recommends following your child’s lead in conversation rather than drilling words. Narrate what you are doing at bath time or while making lunch. “I’m pouring the water. It’s warm.” No special toys needed.

For children using AAC or PECS, model the system yourself. Point to the symbol when you say the word. Repetition without pressure is the whole strategy.

Social and emotional

This domain tracks how your child connects with others, manages feelings, and begins to understand that other people have their own thoughts and needs. It includes attachment, play styles, and emotional regulation.

Regulation does not mean calm. It means your child can return to a manageable state after being dysregulated. For many neurodivergent children, this takes longer and needs more scaffolding. Co-regulation (you staying calm alongside them) is the most effective tool you have, and it costs nothing.

A simple daily habit: name emotions out loud as they happen. “You’re frustrated. The tower fell.” You are building vocabulary and showing them their feelings are real and speakable.

Movement and physical

Gross motor skills (walking, jumping, climbing) and fine motor skills (pincer grip, drawing, buttoning) both live here. Children who are sensory-seeking often develop gross motor skills early; children who are sensory-avoiding may be more cautious physically.

Outdoor play, even in a small garden or a park, covers most of what this domain needs. Climbing, running, and carrying things all count. NHS Best Start in Life is clear that everyday routines and playful practice build these skills more reliably than structured activities.

Cognition, fine motor skills, and self-help

This is the practical domain: problem-solving, memory, attention, and the self-care tasks that matter enormously for school readiness. Feeding, toileting, dressing, and handwashing all sit here.

  • Feeding: offer a range of textures without pressure; let your child touch and explore food before eating it
  • Dressing: break it into steps; start with the last step (pulling a jumper fully over the head) so your child always finishes with success
  • Toileting: follow your child’s readiness cues rather than a calendar age; many neurodivergent children toilet-train later, and that is fine

Pro Tip: For neurodivergent children, sensory modulation matters enormously in self-help tasks. Scratchy labels, tight waistbands, and cold water can make dressing and handwashing genuinely distressing. Removing the sensory barrier often removes the “behaviour.” See our guide on supporting an autistic toddler for practical strategies.

What are the UK checks, and when should you contact someone?

A parent I know described the 9-month review as “the first time anyone actually asked me how I was doing.” That is partly the point. UK health visiting reviews are as much about supporting the caregiver as assessing the child.

The routine review schedule

Review Approximate age What it covers
Newborn 1–2 weeks Feeding, weight, jaundice, general health, maternal wellbeing
6–8 week check 6–8 weeks GP physical exam; health visitor checks feeding, sleep, early social responses
9–12 month review 9–12 months Language, social development, growth, hearing, vision, diet, behaviour, safety
2–2.5 year review 2–2.5 years Language, behaviour, sleep, toilet training, diet, tooth brushing, vaccinations

ASQ-3 questionnaires are typically sent to parents before the 9–12 month and 2-year reviews. Fill yours in honestly, including things your child cannot yet do. The questionnaire is a conversation-starter, not a pass/fail test.

Red flags: when to contact someone now

Do not wait for the next scheduled review if you notice any of the following:

  • Regression: your child loses a skill they previously had (words disappear, stops walking, withdraws socially)
  • No social smile by 8 weeks
  • No babble by 9 months
  • No words by 18 months
  • No two-word phrases by 2 years
  • Not bearing weight on legs by 12 months
  • Persistent feeding difficulties affecting weight gain at any age
  • Any concern about hearing or vision at any age

What to do, step by step

  1. Write it down first. Note the specific behaviour, when it started, and how often it happens. One concrete example is more useful to a health visitor than a general worry.
  2. Contact your health visitor as a first step for most developmental concerns. You do not need a GP referral to speak to your health visiting team.
  3. Ask your GP if you cannot reach your health visitor, if the concern feels urgent, or if regression is involved.
  4. Request a referral if you feel your concern is not being addressed. You can ask for a referral to speech and language therapy (SALT), a community paediatrician, or children’s services. You do not need to wait to be offered one.
  5. Bring evidence. A short video clip of the behaviour, your Red Book notes, and the completed ASQ-3 all help the professional understand what you are seeing at home.

How do you track milestones at home without it becoming a second job?

I started keeping notes on Remy when he was about 14 months. Not because I was anxious (well, partly because I was anxious), but because I kept forgetting what I’d noticed by the time we got to a review. The health visitor would ask a question and I’d go blank. A simple tracker fixed that.

You do not need an app or a spreadsheet. A notes page on your phone or a small notebook works perfectly.

A simple tracking structure

Use five columns, or just five things to jot per observation:

  1. Date
  2. What you observed (specific behaviour, not a judgement — “pointed at the dog and said ‘da’” not “seemed communicative”)
  3. Domain (communication, social, movement, self-help)
  4. What was different (new skill, regression, or change in frequency)
  5. Who was present (you, both parents, nursery key worker)

That last column matters more than it looks. A behaviour that only appears at home, or only at nursery, tells the health visitor something important about context.

Quick daily habits that actually stick

  1. One jot per day, after a routine moment. Bath time, mealtimes, and the school run produce the richest observations because they are repeated and familiar. Thirty seconds is enough.
  2. One photo or video per week. Not posed. Just your child doing something ordinary. A clip of them eating, playing, or getting dressed is worth more than a written description.
  3. Share with your partner or co-carer weekly. Anthony and I do a five-minute catch-up on Sunday evenings. It means we both notice patterns, not just one of us.
  4. Review your notes the night before any health appointment. Pick two or three specific observations to raise. Health visitors have limited time; concrete examples get better responses than “I’m just a bit worried.”

Pro Tip: For self-help tasks like dressing, try backward chaining: teach the last step first so your child always finishes the task themselves. It builds confidence faster than starting from the beginning, and it gives you a clear milestone to log — “pulled jumper over head independently for the first time.” That kind of specific note is gold at a review.

Key takeaways

The most useful thing you can do with any milestone checklist is use it as a prompt for observation, not a scorecard — and bring those observations, written down, to every health visiting review.

Point Details
Variation is normal Milestone lists are guides; neurodivergent children often have uneven profiles across domains.
Four routine UK checks Reviews at 1–2 weeks, 6–8 weeks, 9–12 months, and 2–2.5 years form the NHS baseline.
Regression is urgent Losing a previously held skill requires same-day GP contact, not a wait for the next review.
Track simply and specifically A date, a behaviour, and a domain is enough; one video clip per week adds real value at reviews.
Fidget and Spin sessions Weekly sensory play in Brighton & Hove gives neurodiverse children aged 1–6 a low-pressure space to practise skills across all four domains.

What milestone lists miss, and why that matters

There is something I want to say honestly, parent to parent.

I have read a lot of milestone lists. I read them obsessively when Remy was small, cross-referencing ages, counting words, timing how long he could sustain eye contact. And I understand why parents do that. When you are worried, a list feels like a map. It feels like control.

But a list cannot tell you what it feels like to watch your child light up at a spinning wheel and ignore every toy the list says they should be reaching for. It cannot capture the way Remy learned to communicate in a completely different sequence to the one the charts describe, and how that turned out to be absolutely fine. Lists describe averages. Your child is not an average.

What I have come to believe is that milestone lists are most useful when they prompt a conversation, not when they end one. Bring your observations to your health visitor. Ask the question you are embarrassed to ask. Request the referral if you feel something is being missed. The list is the starting point, not the verdict.

For families navigating neurodivergent development, the Fidget and Spin guide to developmental milestones goes further into what variability actually looks like in practice, and why a “spiky profile” is not a problem to be solved.

FAQ

What is a milestone checklist?

A milestone checklist is an age-ordered list of skills and behaviours most children develop by a certain point, grouped by domain (communication, social, movement, and self-help). It is a guide for observation and conversation with your health visitor, not a pass/fail test.

What are the five major milestone areas?

NHS Best Start in Life describes five broad areas: physical and motor development, cognitive development, language and communication, social and emotional development, and sensory and motor skills. In practice, UK health visiting reviews typically group these into four working domains.

What are some common milestones to watch for?

Common milestones include a social smile by 8 weeks, babbling by 4–6 months, a first word by 12 months, two-word phrases by 2 years, and dressing independently by 5 years. Regression at any age, meaning losing a skill previously held, is the single most important sign to act on immediately.

What types of milestones are there?

Milestones fall into four types used in UK health visiting: communication and language, social and emotional, movement and physical, and cognition with fine motor skills and self-help tasks such as feeding, dressing, and toileting.

When should I contact my health visitor about milestones?

Contact your health visitor any time you are worried, without waiting for a scheduled review. Specific triggers include no social smile by 8 weeks, no babble by 9 months, no words by 18 months, no two-word phrases by 2 years, or any regression in skills your child previously had.
