Why Annual Well-Child Visits Matter From Age 3 and Up

The early years of a child’s life are filled with rapid milestones — first steps, first words, and frequent visits to the doctor’s office. But as toddlers transition into school-aged kids and teens, parents may wonder: If my child isn’t sick, do they really still need to see the doctor every year?

The short answer is yes. While the pacing of doctor visits shifts as kids grow, annual pediatric checkups remain a cornerstone of long-term health, safety, and development.

According to Lauren McCrillis, DO, with Lehigh Valley Health Network, part of Jefferson Health, well-child visits happen frequently in infancy and early childhood — typically every 2 to 3 months. Because babies and toddlers develop so quickly, these close intervals allow pediatricians to closely monitor growth and early milestones.

As children grow older, those appointments space out. Following the American Academy of Pediatrics recommended schedule, visits transition from monthly checkups in early infancy to checkups every 2, 3, and 6 months, before moving to a steady annual schedule once a child turns 3.

“After children turn 3, we start seeing them on a yearly basis unless other concerns come up,” Dr. McCrillis explains. 

Pro tip for parents: You don’t have to wait for your child’s scheduled annual well visit if a worry comes up. If you notice changes in growth, behavior, or health, reach out to your pediatrician’s office anytime.

A routine pediatric visit is comprehensive, covering far more than just a quick physical check. Dr. McCrillis shares what you can expect during a typical appointment:

• Vitals and measurements: A nurse or clinician starts by checking your child’s height, weight, and blood pressure. Depending on your child’s age, they’ll also undergo routine hearing and vision screenings.
• Health and lifestyle discussion: Your doctor or clinician will spend time talking with both you and your child. Expect to discuss everyday habits, including nutrition, physical activity, sleep patterns, behavior, school progress, and any family concerns.
• Comprehensive physical exam: The clinician performs a thorough exam, checking your child’s eyes, ears, mouth, heart, lungs, abdomen, spine, and genitourinary system.
• Vaccines: Any age-appropriate immunizations required to keep your child protected against preventable diseases are given at the end of the visit — sometimes followed by a well-deserved sticker!

Screenings evolve alongside your child’s developmental needs. For infants and toddlers, expect an emphasis on developmental milestones, growth tracking, and early blood tests like hemoglobin and lead levels.

For older children and teens, screenings may expand to include in-office lipid (cholesterol) checks, or confidential mental health screenings for depression and emotional well-being.

The primary goal at every well visit is to confirm that your child is thriving, healthy, and growing appropriately. However, routine checkups are also the best way to catch potential issues and help your child get the support they need. 

“Annual checkups are important to ensure nothing is missed,” explains Dr. McCrillis. “Our hope for the checkup is that your child is healthy and growing well. Unfortunately, this is not always the case.” Issues like subtle developmental delays, high blood pressure, or poor growth trends often show no obvious symptoms at home. Catching these concerns during a routine annual visit allows us to step in early — preventing minor health issues from turning into major complications down the road.

 Regular visits also build a trusting relationship between your child and their healthcare team, making medical care comfortable and routine as they mature. “My goal is to help each child grow and develop to reach their full potential,” says Dr. McCrillis. Every annual checkup gives your child another opportunity to receive guidance from a trusted source and can give you peace of mind that your child’s well-being is supported at every stage.
