Child Development Milestones UK: A Parent's Guide from Birth to 11

A UK parent's guide to child development milestones from birth to 11: Development Matters checkpoints for talking, moving and feelings, NHS reviews, the EYFS progress check and early learning goals, school assessments, and who to talk to if you are worried.

Another child at playgroup is already chatting in sentences, or a friend's toddler walked months earlier, and you wonder whether your own child is on track. Child development milestones should answer that question, but online lists are often contradictory or borrowed from other countries. This guide brings together what official UK sources say about development from birth to age 11: the checkpoints early years practitioners use in England, the NHS health and development reviews, the assessments schools carry out, and what to do if something does not feel right.

One idea runs through the whole article: milestones are signposts, not deadlines. The Department for Education's own guidance describes development as "like a spider's web with many strands, not a straight line". Knowing the typical pattern helps you notice early when a child needs support, and also what a child is unusually good at. That second part is why the British Talent Academy exists.

What are child development milestones?

A developmental milestone is a skill that most children show by a certain age: smiling, sitting, first words, running, taking turns, holding a pencil. Milestones are usually grouped into areas such as communication and language, movement (physical development), and personal, social and emotional development, which covers feelings, relationships and independence.

Different organisations set the bar differently, which is one reason lists disagree. The US Centers for Disease Control and Prevention explains that its milestone checklists include milestones that most children (75% or more) are expected to reach by a given age, to avoid a "wait and see" approach. In England, nurseries, childminders and Reception teachers use Development Matters, the Department for Education's guidance for the early years foundation stage (EYFS). It sets out development "in broad ages and stages", and warns that "the actual learning of young children is not so neat and orderly". Using the same language as the professionals around your child makes conversations much easier.

The UK checks and assessments from birth to 11

Before looking at individual skills, it helps to know when professionals will formally look at your child's development, so you know when to expect feedback and when to raise questions. In England the main points are set out below.

These dates come from the NHS guide to baby reviews, the EYFS statutory framework and GOV.UK's guidance on the national curriculum. If your baby was born prematurely, the NHS explains that their developmental age is calculated from the original due date until they are 2. Scotland, Wales and Northern Ireland have their own systems, so the details above apply to England.

Birth to 12 months: the first year

The first year is about connection as much as skills. Development Matters starts with things like turning towards familiar sounds, gazing at faces, copying facial expressions and enjoying singing and music. Its observation checkpoints for babies include:

• Around 6 months: does the baby respond to familiar voices, turn to their own name and "take turns" by babbling?
• Around 7 months: do they respond to the emotions in your voice?
• Around 12 months: do they babble and use single words, point to share interests, and choose between two objects?
• Around 12 months (movement): can they pull to stand and pick up something small with finger and thumb?
• Around 12 months (social): are they starting to be shy around strangers?

Your health visiting team will send you the Ages and Stages Questionnaire (ASQ-3) before the 9 to 12-month review; the NHS reassures parents not to worry if they cannot fill in all of it. Keep the milestones section of your baby's red book up to date too.

How to help in the first year

The NHS advice on helping your baby learn to talk is simple: look at your baby as you talk, chat about what you are doing during feeding and bath time, sing, and repeat back the sounds your baby makes, which teaches turn-taking. From 6 to 12 months, name and point to things you can both see, share books and play peek-a-boo. The NHS also advises aiming to stop using dummies completely by 12 months, because it is hard to learn to talk with a dummy in your mouth.

1 to 3 years: toddlers find their words and their feet

Between 1 and 3, language and movement accelerate, and the biggest differences between children often appear. Development Matters gives some of its most specific checkpoints for this age.

Communication and language

• Around 15 months: can the baby say around 10 words (they may not all be clear)?
• Around 18 months: is the toddler using at least 20 clear words and understanding some two-word phrases, such as "shoes on"?
• Towards their second birthday: can the child use up to 50 words and put two or three words together, like "more milk"? Around 2, children understand many more words than they say: between 200 and 500.
• Towards their third birthday: can the child use around 300 words, link up to 5 words together, and follow instructions with three key words, like "Can you wash dolly's face?"

Development Matters adds an important note: watch out for children whose speech is not easily understood by unfamiliar adults, and consider whether a hearing test might be needed.

Physical development

Around their second birthday, Development Matters asks whether a toddler can run well, kick a ball and jump with both feet off the ground. Around their third birthday, can they climb confidently, catch a large ball and pedal a tricycle? Tearing paper, mark-making and handling spoons and brushes build the hand strength later needed for writing.

Personal, social and emotional development

By around 18 months, a toddler is typically curious about their world and wants to be noticed by you. Around 2, children start to see themselves as a separate person, deciding what to play with, eat and wear. Between 2 and 3, many start to enjoy the company of other children. Frustration is normal: Development Matters suggests helping toddlers name feelings such as "sad" or "angry".

The two-year checks

Two checks come together at this age. The NHS offers a health and development review at 2 to 2½ years covering movement, speech, social skills, behaviour, hearing and vision, with an ASQ-3 questionnaire beforehand. If your child attends nursery or a childminder, the EYFS statutory framework also requires a progress check between 2 and 3, with a short written summary of the prime areas. It must highlight where your child is progressing well, where support might be needed and any concern about a possible developmental delay. NHS tips for this stage include replying with slightly longer sentences ("sock off" becomes "yes, we're taking your sock off") and switching off background TV so your child can hear you.

3 to 5 years: preschool and Reception

From 3, development becomes more social and more visible to others. Development Matters checkpoints for this age include:

• Around 3: can the child shift from one task to another when you use their name, and sometimes share or take turns with adult guidance?
• Around 4: are they using sentences of four to six words, joined with "because", "or" and "and", and answering simple "why" questions?
• Around 4 (social): do they take part in pretend play with different roles and negotiate conflicts in play?
• 3 and 4-year-olds (physical): learning to hop, skip, use alternate feet on stairs, snip with scissors and show a dominant hand.

The early learning goals at the end of Reception

The EYFS has seven areas of learning. Three prime areas (communication and language; physical development; and personal, social and emotional development) are described in the statutory framework as particularly important for learning and forming relationships. Four specific areas (literacy, mathematics, understanding the world, and expressive arts and design) build on them. In the final term of Reception, and no later than 30 June, teachers complete the EYFS Profile, judging whether each child is at the expected level or "emerging" on each of 17 early learning goals. The school must share the results with you and explain how you can discuss them.

At the expected level, a 5-year-old will, for example, hold a pencil using the tripod grip in almost all cases, use scissors, paint brushes and cutlery, move energetically, manage their own basic hygiene including dressing and going to the toilet, and express ideas in full sentences using past, present and future tenses.

What the national figures show

According to the Department for Education's EYFS Profile results for 2024/25, 68.3% of children in England had a good level of development at the end of Reception, and 66.9% were at the expected level across all 17 early learning goals. On average, each child reached the expected level in 14.11 goals. Literacy had the lowest percentage of children at the expected level of the seven areas, and writing was the lowest of the 17 goals.

The breakdowns matter. Girls (75.3%) were more likely than boys (61.6%) to reach a good level of development, autumn-born children (75.6%) more likely than summer-born children (61.1%), and children not eligible for free school meals (72.5%) more likely than those eligible (51.3%). A summer-born child can be almost a year younger than classmates measured against the same goals, so being "behind" at 4 or 5 often reflects age, not ability.

5 to 11 years: primary school development

Development does not stop when school starts. Speech and Language UK's 5 to 7 guide says that by 7, children will usually follow long instructions, understand that the same word can mean two things, join sentences with "so" and "because", and talk clearly enough that unfamiliar people understand them almost all of the time.

By 11, according to its 7 to 11 guide, children will usually use sentences of between 8 and 10 words, make predictions and draw conclusions, understand other points of view, and start conversations with people they do not know. Signs to look out for include only following part of an instruction, finding it hard to make up stories, or struggling to make and keep friends.

School assessments in key stages 1 and 2

Schools in England also carry out a few national assessments. GOV.UK's key stage 1 and 2 guide explains that in Year 1, children read 40 words aloud in the phonics screening check in June, retaking it in Year 2 if needed. Key stage 1 tests in Year 2 are optional. In Year 4, the multiplication tables check has 25 on-screen questions, with 6 seconds for each, on times tables up to 12; there is no pass mark. In Year 6, national tests in reading, maths, and grammar, punctuation and spelling are held in May, with results in July.

These checks measure a narrow slice of what a child can do. They say little about creativity, physical skill, leadership, empathy or perseverance, all of which matter for a child's long-term success and wellbeing. That gap is one we explore in The Core Problem and The Hidden Cost.

Friendships, independence and confidence

Primary school is also when independence, friendships and confidence grow. The end-of-Reception goals already include "independence, resilience and perseverance in the face of challenge". A child who avoids anything they might fail at may benefit from low-pressure chances to try new things; our guide to extracurricular activities has ideas by age and budget.

When to talk to a professional

Every child is different, and a single late milestone is rarely a cause for alarm on its own. But you know your child best, and professionals would much rather hear from you early. Development Matters itself says that when children are at earlier stages of development than expected, "it is not helpful to wait for them to become 'ready'". Consider getting advice if:

• your child seems to be losing skills they used to have;
• your child's speech is hard for unfamiliar adults to understand by around age 3, or you have any concern about their hearing;
• your child seems worried, sad or angry for much of the time, cannot be calmed, or becomes extremely upset by certain sounds, smells or tastes (all mentioned as reasons to work with parents and other agencies in Development Matters);
• a nursery, childminder or teacher has raised a concern, or the 2-year progress check highlights an area needing support;
• your school-age child only follows part of an instruction, struggles to join group conversations, or is struggling at school and nobody is sure why.

For under-5s, start with your health visitor, GP or nursery key person; the NHS notes you can also refer your child to a speech and language therapist yourself. At school, speak to the class teacher and then the special educational needs co-ordinator (SENCO). GOV.UK's guide to children with special educational needs and disabilities explains that support can include SEN support in school or, for more complex needs, an education, health and care (EHC) plan. Your local Information, Advice and Support (IAS) Service can also advise.

Milestones show strengths as well as needs

The same careful observation that spots delay also reveals where a child is ahead: the toddler with a huge vocabulary, the 4-year-old who builds elaborate structures. If your child is consistently ahead, see our guide to the signs of a gifted child and our article on gifted and talented provision in UK schools.

Uneven profiles are normal too: a child can be late to talk yet advanced in spatial reasoning. That is why the British Talent Academy looks at a child's whole talent profile rather than a single score, using structured observation across many kinds of activity.

How parents and schools can work together

Development Matters says a strong, respectful partnership between parents and settings "sets the scene for children to thrive". The Education Endowment Foundation's guidance report Working with Parents to Support Children's Learning notes that parental engagement is consistently associated with better academic outcomes, and that effective engagement can lead to learning gains of +3 months over a year.

• Share what you see at home. Settings only see part of your child: tell them about interests, new words, worries and achievements.
• Ask about next steps. After the 2-year check or the EYFS Profile, ask what happens next and how you can help at home.
• Treat reports as conversations. Schools in England must send a report on progress by the end of each summer term and talk it through with you.
• Keep it everyday. Talking, reading together, play and outdoor time are the foundations.
• Look for patterns over time. BTA's parent dashboard is designed to make that picture easier to see, and our school partnership page explains how we work with schools.

Next steps

Child development milestones are most useful when they lead to action: a timely conversation if something seems off, and the right opportunities when a strength appears. The British Talent Academy is building an early talent intelligence platform to help families and schools understand each child earlier and more deeply, starting with our founding pilot in Sheffield.
