Health review: 3-year-old check-up

2 min readUpdated November 21, 2025

Three-year-olds are great fun to bring in for a check-up. They're so curious about what's going on and eager to cooperate. They love to report their name and age and tell the doctor or nurse about their life. They're also interested in their bodies, and aren't as defensive about them as many two-year-olds are. Try not to come in at nap time or on a completely empty tummy; no one will get the best out of the experience.

Key Takeaways

  • An important milestone. The 3‑year review marks a key opportunity to check how your child is growing and developing. Try to book it at a time when they’re well‑fed and rested. 

  • What the check‑up covers. Expect measurements of height, weight and likely blood pressure, along with hearing and vision screening, motor skills and communication tests (often via a drawing or other activity). 

  • Be ready to share. Your health visitor or GP will ask about your child’s behaviour, sleep, toilet‑training, diet, social interactions and any developmental concerns. 

  • Raise any red flags. If you’ve noticed delayed speech, difficulty interacting with peers or other unusual behaviour, mention it – early conversations can guide timely support. 

  • Talk readiness and change. This appointment is a good chance to discuss preschool readiness, any household changes, and ask about any resources or

At this visit, your provider will probably:

  • Weigh and measure your toddler.

  • Check his blood pressure

  • Ask him some questions and give him instructions. Don't try to help your child – the provider is interested in his response. Stay in the room and near him as reassurance, but see how much he can handle on his own.

  • Your provider will test your child's vision and hearing (until now, your baby probably has had eye and ear tests only if you or your provider suspected a problem). Let your provider know if there is a family history of early vision or hearing problems.

  • Some providers check urine samples. Let your provider know if urinating is painful for your child, if he dribbles or can't hold his urine, or if he's gone back to wetting after being toilet-trained.

  • Your child may also be asked to make a drawing, which provides helpful information about your child's development and well-being. You may want to bring in some of his creations from home, too.

Your provider will want to know:

  • If your baby seen another healthcare provider since the last visit? If so, why? What was the outcome of that visit, and was any medication or treatment prescribed?

  • Does your baby jump, kick a ball or ride a tricycle or other toddler-style three-wheel bike?

  • Does he know his name?

  • Can he play well with other children?

  • Have his tantrums increased?

Talk it over

  • If your child is in day-care or pre-school, the teachers there may have mentioned concerns. Talk these over with your provider.

  • If your child hasn't been in day-care or pre-school yet and you're considering enrolling him, your provider may be able to give you some guidance on finding a good one.

  • If grandparents or other relatives have mentioned any concerns about your child, discuss them with your provider.

  • Let your provider know if your child seems to be having problems eating or sleeping. If he snores or coughs at night, ask what to do about it.

  • Tell your provider if you are on a special diet, such as vegetarian or low cholesterol. Your provider can help you ensure that your growing child and the whole family get the proper nutrition.

  • Discuss where he's at with toilet-training. Mention if there has been any back-sliding on this issue. You may need some guidance.

  • If you're having trouble with discipline, discuss it now.

Speak up!

The following items are of special concern, so be certain to tell your healthcare provider if your child:

  • Isn't speaking in real sentences or asking questions using the 'w' words (who, what, where, when and why).

  • Isn't following stories or showing any interest in books.

  • Always stands too close to the TV or likes the volume turned up high.

  • Squints.

  • Has a lot of difficulty separating from you.

  • Isn't really interacting with other kids in a group setting.

  • Isn't happy most of the time.

  • Doesn't know his name and age.

Also be sure to mention:

  • If a household member or someone who has frequent contact with your child has tuberculosis, hepatitis or another serious infectious disease. Your child may need testing or treatment.

  • If there's been an outbreak of diarrhoea or any contagious disease in his school or day-care centre, or at your office. Your child may need special tests or vaccines.

  • If there has been any major change in your family or circumstances.

  • If you have no health insurance for your child.

Finally, a baby check-up at three years is an opportunity for you to discuss any concerns with your provider and make sure that your child is on the right track of his development. So take the opportunity!
