The short answer
A US three-year checkup covers growth and physical health alongside language, play, social interaction, daily skills, nutrition, sleep, toilet learning, teeth, vision, and safety. Bring your concerns and records. A CDC milestone checklist may help the conversation, but it does not replace a diagnostic assessment or standardized developmental screening.

Keep in mind
- Growth trends matter more than one measurement or percentile.
- Bring examples from home and childcare, especially changes or lost skills.
- Screening and vaccination plans depend on records and individual needs.
- Do not wait for the scheduled visit if a significant concern arises.
How are growth and physical health reviewed?
Your clinician considers weight, standing height, and age-appropriate BMI alongside previous measurements, health history, and a physical examination. A trend is more informative than aiming for one percentile.
Which developmental topics may come up?
Discuss conversation, questions, speech clarity, joining peers’ play, drawing, using a fork, dressing, and other daily skills. If behavior differs between home and childcare, bring examples from both settings.
Why discuss vision, teeth, and other screening?
AAP’s three-year visit guide includes vision and oral health screening. Discuss brushing, dental visits, and nutrition. Other screening and vaccinations depend on previous records, local guidance, and individual risks; your clinician determines the plan.
What should you bring?
Bring growth and vaccination records, a medicine list, recent health information, and relevant family history. Write your three main questions about sleep, food, bowel habits, toilet learning, speech, movement, hearing, vision, or behavior; childcare observations can help too.
How can you prepare your child?
Explain simply that the clinician may measure them, listen to their heart, and ask questions. Practise with a toy if useful. Avoid using the visit as punishment or threatening an injection; give your child time to respond and support them without forcing answers.
When to seek support
Some signs need emergency help; other concerns can be discussed with your child’s healthcare team.
- Loss of previously acquired language, movement, play, social, or daily-living skills needs prompt assessment.
- Poor growth, persistent pain, recurrent vomiting, or symptoms affecting daily functioning should not wait for the routine visit.
- Severe breathing difficulty or unresponsiveness is an emergency: call 911.
- Strong ongoing concerns about hearing, vision, speech, movement, or behavior deserve assessment.
