Find some useful information now your child is 3 to help to keep them healthy and able to learn:

  • speech, language and communication - when your child starts school they will need to ask for things, talk to their friends and be able to follow instructions. Talking at home as you make a meal together, while you're out shopping together or on the bus, reading stories and singing can all help your child’s speech, language and communication. Find speech, language and communication advice
  • sleep - children of this age need to go to sleep early in the evening and sleep through the night to help them grow and develop. No screen time one hour before bed will help them to relax and fall asleep. Find healthy sleep tips for children
  • exercise - children of this age need around 3 hours of physical activity a day to help them grow and develop. Running, jumping, climbing and playing outdoors are all great for your child. Read physical activity guidelines for children (under 5 years)
  • going to the toilet - learning to use the toilet rather than a potty is an important part of growing up. When your child starts school it will help if they can be independent using the toilet. Your child will want to be like their friends and wear underwear rather than pull-ups. Read information and advice about learning to use the toilet
  • social interaction is very important to help your child to be school ready. York Family Information Service will help you with information on local social groups such as stay and play groups or music groups. They will also support you with 3 year funding and available settings like nurseries or childminders. Telephone: 01904 555444 or email: [email protected]
  • vaccinations - a reminder that your child requires their next vaccination at 3 year 4 months. Flu vaccination (nasal spray) each winter after your child turns two years. Read guidance from the NHS about immunisations and when to have them
  • vitamin D - the department of health recommends children should have a vitamin D supplement containing 10mcg daily, up to the age of 4 years old
  • teeth - should be brushed twice a day with a fluoride tooth paste (1000ppm fluoride). Avoid sugary drinks and snacks, so teeth don’t decay. Parents and carers should help to brush teeth until the age of 7 years old. Bottles and dummies should be stopped as these can cause problems with teeth and speech. Read more about children's teeth. We advise you to register your child with a dentist and attend for regular check-ups if your child hasn’t already. This helps to spot problems early. Find an NHS dentist

Remember that your child is an individual.
