Well-child visits are planned visits for prevention, growth, development, and questions that may not fit into a sick visit. The exact tests, vaccines, and timing depend on age, health history, local requirements, and the current recommendations.

When to Get Urgent Help

A routine visit is not the right setting for a child who may be seriously ill or injured.

CALL 911 NOW

  • Severe trouble breathing, blue or gray lips or face, a seizure, a child who is limp or unresponsive, or another life-threatening emergency.

  • ·     Immediate danger to the child or another person.

CONTACT YOUR CHILD'S HEALTHCARE PROFESSIONAL TODAY

  • A young infant with fever, a child who looks very ill, significant breathing difficulty, dehydration, severe pain, a rapidly worsening symptom, or a concern that should not wait for the next scheduled checkup.

  • A developmental, behavioral, learning, emotional, or safety concern that is affecting daily life. Do not wait for a routine visit if you are worried.

Why Well-Child Visits Matter

  • Prevention: recommended immunizations, safety guidance, nutrition and physical-activity counseling, and discussion of family priorities.

  • Growth and health: measurement of growth and a focused examination; vision, hearing, blood pressure, laboratory, or other screening may be recommended at particular ages or because of a child's history.

  • Development and well-being: discussion of play, learning, language, behavior, sleep, mood, relationships, and school. Parents and caregivers often notice important changes first.

  • A continuing relationship: regular visits help families and clinicians know what is typical for the child and address concerns earlier.

The Current Well-Child Schedule

The AAP/Bright Futures preventive-care schedule begins in the first week of life and continues through young adulthood. It includes frequent visits in infancy, then yearly visits for most children. Because the schedule and recommended services can change, use the current AAP schedule and confirm the next visit with your child's healthcare professional.

What Families Can Expect

Before the visit

  • Write down your three to five most important questions. Include changes in sleep, eating, stools, pain, behavior, learning, moods, medication, school, sports, or safety.

  • Bring the immunization record, a list of medicines and supplements, forms needed for school or sports, and relevant reports from teachers, therapists, or other clinicians.

  • Ask whether your child needs to fast, complete questionnaires, bring glasses or hearing devices, or prepare for laboratory testing.

At the visit

  • The child may have growth measurements, a health history review, examination, recommended screening, and discussion of preventive care. The exact components differ by age and individual needs.

  • The clinician may speak privately with an older child or adolescent for part of the visit. Private time supports honest discussion of health, mood, safety, relationships, and substance-use concerns while respecting appropriate family involvement.

  • The visit is a good time to review vaccines, side effects to expect, and questions about an individual vaccine plan.

After the visit

  • Keep the after-visit summary, updated immunization record, referrals, and test instructions. Follow up promptly on an abnormal screening result, referral, or test that needs to be repeated.

  • If a new concern develops, contact the child's healthcare professional rather than waiting many months for the next routine visit.

Developmental and Behavioral Screening

Developmental monitoring happens over time through conversations and observation. Screening is a more formal questionnaire or tool used at recommended ages or whenever a family, teacher, or clinician has a concern. It is not a diagnosis; it helps decide whether further assessment or support may be useful.

  • AAP guidance calls for standardized developmental screening at 9, 18, and 30 months, and autism-specific screening at 18 and 24 months. Screening may also be appropriate at other times when there is a concern.

  • ·Share milestones and concerns from home, child care, or school. A child who loses a skill, has a major communication change, or is not progressing as expected should be evaluated promptly.

Special Circumstances

  • Children with chronic medical conditions, developmental differences, mental-health needs, medications, prematurity, prior abnormal tests, or complex family circumstances may need additional visits or screening.

  • A sports form, school form, camp form, travel requirement, or medication refill may require a separate appointment. Ask early rather than assuming it can be completed during a routine visit.

  • If insurance, transportation, language, or scheduling makes preventive care difficult, tell the healthcare team. They may be able to help identify options.
