Critical development milestones keep kids on track for starting school, and checkups are an opportunity to catch any chronic illnesses early.

When your child is between the ages of 3 and 6, the routines of well-child visits with your pediatrician can fall off the calendar.

They aren’t toddlers or babies anymore, and they haven’t started school. Sometimes life takes over.

But these are important years for well-child visits. Critical developmental milestones should be met during these ages to keep kids on track for starting school. This is also an opportunity to catch any chronic illnesses before they get more difficult to treat.

“These years are absolutely vital times to see your pediatrician regularly to ensure optimal development and kindergarten readiness,” said Matthew D. Kinney, M.D., pediatrician with Norton Children’s Medical Group, affiliated with the UofL School of Medicine..

Helping kids catch up to developmental milestones before they start school can set them on the right path for the rest of their school years.

“We know that kids who start kindergarten behind other kids in terms of academic capabilities likely will stay behind throughout their school years, and those who start out ahead of peers will stay there,” Dr. Kinney said.

Your pediatrician also can guide you through your child’s behavioral development.

Ages 3 to 6 are also important for catching early signs of a chronic illness or health issue, ranging from cavities, obesity and attention-deficit/hyperactivity disorder (ADHD) to more serious conditions such as diabetes and cancer.

In the 3-to-6-year-old age range, chronic conditions that pediatricians see more than others include asthma, autism and ADHD, along with behavioral and mood concerns, sleep issues, dental health concerns, allergies, skin conditions, obesity and diet concerns, according to Dr. Kinney.
