Well-Child Visit Schedule by Age: When Are Checkups Due?

What is the recommended well-child visit schedule by age?

The American Academy of Pediatrics recommends well-child visits at birth and within the first week, then at 1, 2, 4, 6, 9, 12, 15, 18, and 24 months. From age 3 onward, children have one checkup per year through age 21. The schedule is more frequent in infancy because growth and development change fastest then.

Pediatricians in the United States generally follow the Bright Futures periodicity schedule published by the American Academy of Pediatrics (AAP), which aligns with recommendations from the Centers for Disease Control and Prevention for developmental monitoring and screening. The table below summarizes the typical timing.

The frequent early visits are not arbitrary: infancy is when feeding problems, growth concerns, and developmental delays are most easily caught and addressed. As children get older, the spacing widens because healthy children need less frequent monitoring, though the yearly visit remains important for screening, immunizations, and sports or school paperwork.

Practices sometimes shift a visit by a few weeks to combine it with a vaccine or to fit a family's schedule. At Alta Loma Pediatrics in Rancho Cucamonga, the team follows the CDC-recommended immunization schedule endorsed by the AAP and can help families plan which visit is due next.

What happens at each well-child visit at different ages?

Every well-child visit includes measurements, a physical exam, and developmental and behavioral screening, but the focus shifts by age. Infancy centers on feeding, growth, and sleep; toddler visits emphasize language, behavior, and safety; school-age visits cover vision, hearing, and learning; teen visits add mental health and risk screening.

Well-child checkups share a common structure: height and weight (and head circumference in infants), a head-to-toe exam, a review of development and behavior, vaccine review, and time for parent questions. What changes is the emphasis.

• Newborn and infant visits: weight gain, feeding (breast or formula), jaundice, sleep safety, and early developmental milestones.
• Toddler visits (12–24 months): language development, walking and motor skills, autism screening (typically at 18 and 24 months), tantrums, and safety-proofing.
• Preschool and school-age visits: vision and hearing screening, speech and learning concerns, school readiness, and kindergarten or sports physicals.
• Adolescent visits: growth and puberty, mental health and mood screening, social and school stress, and private time with the clinician.

Many of these visits also include a physical and the paperwork schools or sports leagues require. Pediatric offices that offer school and sports physicals, including kindergarten-entry physicals, can often combine that form with a scheduled checkup so families avoid a second trip.

Because visits are brief, it helps to write down questions and any symptoms beforehand. A pediatrician who takes time to listen can connect developmental, behavioral, and family context rather than treating each concern in isolation.

How often should a child see the pediatrician after age 3?

After age 3, healthy children typically see the pediatrician once a year through age 21. Yearly visits are still needed even when a child looks well, because they cover growth tracking, vision and hearing screening, developmental and mental health checks, and vaccines due at ages 4–6, 11–12, and 16.

Once a child reaches age 3, the schedule settles into a single annual checkup. That yearly rhythm continues through adolescence and young adulthood, generally until age 21. Missing a year is easy to do when a child seems healthy, but several things are timed to those visits.

1. Vaccines: booster doses are due around ages 4–6, 11–12, and 16, and annual influenza vaccination is recommended for most children.
2. Screening: vision and hearing checks, anemia and lead screening at certain ages, and mental health screening in adolescence.
3. Growth tracking: a single height and weight measurement means little, but a series over years shows whether a child is following their curve.
4. School and camp forms: physicals and immunization records are usually needed on an annual cycle.

Same-day sick visits do not replace the annual exam, and the annual exam is not a substitute for care when a child is ill. If it has been more than a year, the practical step is to call the office and schedule the next checkup rather than waiting for an illness to prompt a visit.

Families in Rancho Cucamonga, Alta Loma, Upland, Ontario, and Chino Hills can call (909) 581-0008 to confirm when the next well-child visit is due or to review vaccine records before booking.

Which vaccines are due at each well-child visit?

Vaccines are timed to well-child visits: hepatitis B at birth, DTaP, IPV, Hib, PCV, and rotavirus in infancy; MMR, varicella, and hepatitis A at 12–15 months; boosters at 4–6 years; Tdap, HPV, and meningococcal at 11–12; and MenB at 16–18. Influenza is annual for most children.

Immunizations are a core reason the well-child schedule is spaced the way it is. Each visit is an opportunity to give vaccines on the CDC-recommended schedule endorsed by the American Academy of Pediatrics. The table below shows the typical timing; your pediatrician will confirm what is due based on your child's record.

Influenza vaccine is recommended annually for most children starting at 6 months of age. Some children with certain health conditions need additional vaccines or an accelerated schedule; that is a conversation for the visit, not a decision to make from a table alone.

Bringing an up-to-date immunization record to every visit helps the pediatrician avoid duplicate doses and catch any that were missed. If a dose was delayed, the office can plan a catch-up schedule rather than starting over.

How is a well-child visit different from a sick visit?

A well-child visit is a scheduled checkup for a healthy child that covers growth, development, screening, and vaccines. A sick visit addresses a specific symptom or illness, often same-day. Sick visits do not replace annual checkups, and checkups are not a substitute for care when a child is ill.

Parents sometimes wonder whether a problem can wait for the next checkup or needs its own appointment. The distinction is straightforward: well-child visits are preventive and planned, while sick visits are problem-focused and often urgent.

• Purpose: well-child visits screen for problems that are not yet visible; sick visits diagnose and treat a current complaint.
• Scheduling: well-child visits are booked in advance on the periodicity schedule; sick visits are often same-day.
• Content: checkups include measurements, developmental screening, and vaccines; sick visits focus on the history and exam relevant to the symptom.
• Paperwork: school, sports, and camp forms are usually completed at well-child visits, not sick visits.

There is an overlap: a concern raised at a checkup may lead to further evaluation, and a sick visit may reveal something that warrants a follow-up checkup. But skipping annual exams because a child had a few sick visits during the year leaves gaps in growth tracking, screening, and immunization.

When a child is ill, call the office to see whether a same-day appointment is available. When a child is due for a checkup, schedule it even if the child seems perfectly well — that is the point of preventive care.

What if my child has missed a well-child visit?

If a well-child visit was missed, call the pediatrician to schedule a catch-up appointment. The office can review vaccine records, update growth charts, and determine whether any screenings are overdue. There is no need to restart the schedule; missed visits are simply picked up from where they left off.

Life gets busy, and it is common for a family to realize a checkup was skipped. The important step is to resume the schedule rather than wait for the next illness or school form deadline.

1. Call the office and explain that a well-child visit was missed. The staff can find the next available appointment and advise what to bring.
2. Gather records: immunization history, any labs or imaging done elsewhere, and a list of medications. If the child saw a specialist, bring those notes as well.
3. Expect a review: the pediatrician will update measurements, check development and behavior, and identify any vaccines or screenings that are due.
4. Plan catch-up vaccines if needed. Most delayed doses can be given without restarting the series.

For families who are new to a practice, the first visit is also a chance to establish a relationship. At Alta Loma Pediatrics, new patients are welcome, and arriving 20 minutes early with records helps the first appointment run smoothly. The practice accepts most major insurance plans and offers reasonable fees for uninsured families.

If it has been more than a year since the last checkup, calling (909) 581-0008 is the fastest way to confirm what is due and get back on track.
