Development milestones – your child at 4 years

Most children reach development milestones within the anticipated age range, but some reach them more quickly or take a little longer. Many children reach certain milestones, for example language, at an earlier age than others while developing other skills in the typical range.

Your preschooler still needs plenty of sleep. By their fourth birthday children need 10 to 13 hours of sleep a day. They might have a nap during the day, but often 4 year olds have no daytime naps.

If you have to wake them most mornings and they are cranky or overtired during the day, your child probably needs more sleep.

A healthy diet will also help your preschooler grow and develop. It’s normal for some preschoolers to be fussy eaters or go through a fussy stage. Keeping mealtime fun while continuing to present a variety of options to your child will help them learn to try and like new flavours and textures.

If you’re concerned about any aspect of your child’s development, talk to your doctor.

Physical and skills milestones

By the age of 4, you child will probably be toilet trained. They will be able to wash their hands and face, and with some help from you, clean their teeth. They’ll be dressing themselves, although shoelaces and buttons may be difficult.

By now they will be improving their ball skills, riding a tricycle, using pencils and scissors and drawing. They will be learning to balance on one foot and hop.

Preschoolers are curious about their bodies and those of family members which can form part of playing ‘mums and dads’ or ‘doctors’.

Childhood sex play — wherein children occasionally and spontaneously show interest in other children’s bodies or genitals — is very common among preschoolers and in the early school years. It’s part of their general curiosity about bodies.

If you’re concerned about how your child behaves during childhood sex play or how they talk about it or about body parts, talk to your doctor or another qualified health professional.

Emotional milestones

Between the ages of 3 and 4, your child starts to have a better understanding that their bodies and feelings are their own. They will also have a better grasp of how emotions such as joy or sorrow feel and how to describe those feelings.

In this age range, children get better at handling their emotions. Improving communication skills enable them to talk about their needs and wants, so you’ll notice fewer temper tantrums.

Self-esteem helps children have the confidence and courage to try new things, feel liked and accepted and feel proud of themselves. It also helps them cope with feelings of sadness or worry. You can help your child build self-esteem by encouraging them to learn and try new things, praising their efforts more than results and by avoiding harsh criticism.

Along with developing self-esteem, your child will be forming friendships and may enjoy playing in small groups where they will practice how to play with other children and what’s acceptable when playing with their friends.

It’s very common for children to develop imaginary friends, which are a result of healthy imaginations. You may recognise a name or description of an imaginary friend from a book, television or toy, or the friend may be completely imagined. Your child will stop playing with their imaginary friend when they are ready.

Thinking and language milestones

By the time your child is 4, you can expect to have conversations with them that involve several hundred new words in sentences of 6 or more words.

By their fourth birthday, preschoolers usually:

  • understand most of the instructions you give about familiar things and places, for example, ‘please put your cup on the table’
  • can be understood by other people
  • recognise and name objects and parts of objects in books and in real life
  • understand concepts such as comparing things (‘big’ or ‘small’, ‘thin’ or ‘thick’), and locations (‘in’, ‘under’)
  • recite familiar rhymes and sing familiar songs
  • ask a lot of questions about the world and how it works — ‘why’ and ‘where’ and ‘when’
  • begin identifying and copying letters, numbers and colours
  • start to understand time
  • know and tell others their name and age

Your child’s language is developing very quickly at this time. Find out more about speech development in children.

Helping your child’s development

Your preschooler will enjoy running, tumbling and rolling, all of which use up energy and help them to deal with their emotions while continuing to develop their growing bodies. Try to give your child lots of chances to participate in physical activity. Encourage your child to play in sand or mud and get ‘messy’, to dance to some music, to climb and explore in nature and navigate playground equipment.

Your preschooler may also enjoy:

  • drawing and painting with pencils, crayons, paints and paper
  • dress-up and pretend games
  • reading books with you, singing and reciting rhymes, and dancing
  • cooking with you, which gives you the chance to introduce numbers and concepts such as weight and size
  • building things with blocks

If you’re concerned

While different children reach milestones at different times, most children should have developed these skills and be enjoying these activities by their fourth birthday.

You should talk to your doctor or child health nurse if you have concerns about any of the milestones described or if you notice that your 4-year-old:

  • isn’t using sentences of more than 3 words
  • doesn’t seem to understand 2-part commands, such as ‘sit on your chair and pick up your book’
  • doesn’t pretend during play
  • seems to overreact with explosive tantrums over small things or when you leave them
  • often trips when walking or running
  • isn’t improving when using pencils or crayons and isn’t able to draw simple shapes
  • has difficulty dressing or using the toilet
  • doesn’t seem to see things or hear you
  • has lost skills they once had

Vaccinations

At age 4, your child should receive vaccinations against diphtheria, tetanus, acellular pertussis (whooping cough) and polio (DTPa-IPV).
