Pediatrician

Medically Reviewed.Last updated on 06/30/2026.

Picking your kid’s pediatrician can feel like a big choice. How do you decide who to entrust with your child’s health and well-being? It helps to know what pediatricians do and weigh your choices. You can also ask for recommendations from loved ones or healthcare providers you already see. Finding a pediatrician who’s a good fit can make a big difference.

What Is a Pediatrician?

Pediatricians ensure your child is growing, healthy and well, but they’re also your main resource when your child is sick.
Pediatrician handle a wide range of care. Much of their job revolves around wellness, primary care and illness prevention.

Pediatricians are doctors who specialize in caring for kids of all ages. Pediatricians care for children starting at birth and through all stages of development. Some types of pediatric care continue after a child reaches adulthood, up to 21 years old.

Some pediatricians focus on primary care, meaning preventive care, annual checkups and ordinary sick visits. Others specialize and focus on specific types of diseases or areas of care.

While pediatricians mainly focus on children’s physical health, that isn’t all they do. They’re trained to help with children’s emotional and social development, too.

Role and responsibilities of a pediatrician

Most pediatricians focus on primary care. That includes:

  • Regular health and wellness checkups (also called well-baby or well-child visits)
  • Physical exams
  • Tracking your child’s physical, emotional and social development
  • Diagnosing and treating illnesses, injuries and other health conditions
  • Preventive care, like screenings and vaccinations
  • Prescribing medicines
  • Listening to parents’ and caregivers’ concerns and providing guidance (like how to manage certain phases of development)
  • Referring families to specialists if needed
  • Reassuring parents and children who may be nervous or scared about something that’s happening

When should my child see a pediatrician?

When your child should see their pediatrician depends on a few things. One big factor is their age. Another is the reason for the visit. And that’s after you find a pediatrician for your child in the first place.

Well-child visits

Your newborn should have two well-child visits before they reach 1 month old. Their first well-child visit with their pediatrician should happen within 72 hours of taking your baby home from the hospital. (If you're having your baby at home or in another place, ask their pediatrician in advance when their first visit should be.) Their second visit should be when they’re between 2 and 4 weeks old.

After that, your child’s pediatrician will recommend well-child visits at:

  • 2 months
  • 4 months
  • 6 months
  • 9 months
  • 12 months
  • 15 months
  • 18 months
  • 2 years
  • 2 1/2 years
  • 3 years

These timed visits happen so your child’s pediatrician can track how your child is developing. They’ll look and check for key infant and toddler development milestones. They’ll also offer recommended vaccines.

Once your child reaches 3 years old, well-child visits usually only need to happen once a year. Your child’s pediatrician will tell you if there’s a reason why your child might need visits more often.

Sick child visits

Sick child visits are for any time your child has an illness that may need professional medical attention, but it isn’t urgent or an emergency.

What if you aren’t sure how serious the situation is?

When your child seems to be feeling unwell and you aren’t sure what’s going on, but it doesn’t seem serious, it’s a good idea to call their pediatrician’s office. Your child’s pediatrician or their staff can ask questions and help guide you on what to do.

If it’s something you can manage on your own at home, they can tell you how. If your child needs to come in for a visit, they can schedule one for you. And if it’s something that could be more serious, your child’s pediatrician can tell you where to go and what to do.

If it’s outside normal hours for your child’s pediatrician, many pediatric offices still have nurses or other trained healthcare professionals answering the phone. They can help you determine how serious the situation is. But when in doubt, it’s best to err on the side of caution. That may mean taking your child to the nearest hospital or calling your local emergency number.

Additional Common Questions

What education do pediatricians need?

After finishing college and medical school, a doctor who wants to become a pediatrician has to do a three-year pediatric residency. They can also go even further and do fellowship training to go into a pediatric subspecialty.

Even for people who complete college and med school at a faster pace, it takes at least 11 years to become a pediatrician. And pediatricians who choose to specialize may add another two to six years of specialty fellowship training.

What areas can pediatricians specialize in?

There are over a dozen subspecialties for pediatricians. Many of them are the child-specific version of a specialty that also exists for adults. The American Board of Pediatrics oversees most of these, but also has partnerships with other medical boards for some of them. Subspecialties with American Board of Pediatrics involvement include:

  • Cardiology (heart and circulatory)
  • Critical care medicine (caring for children who are extremely ill)
  • Emergency medicine (treating potentially serious conditions and providing stabilizing care when further treatment is needed)
  • Endocrinology (hormone and metabolic)
  • Gastroenterology (digestive)
  • Hematology-oncology (cancers and blood disorders)
  • Hospice (end-of-life care) and palliative medicine (symptom relief and comforting care)
  • Hospital medicine (in-hospital needs and care)
  • Infectious diseases (conditions spread by other people, animals, etc.)
  • Medical toxicology (diagnosing and treating toxic exposures)
  • Nephrology (urinary tract)
  • Pulmonology (respiratory tract)
  • Rheumatology (immune conditions)
  • Sleep medicine (sleep disorders)
  • Sports medicine (athletics and mobility)
  • Transplant hepatology (liver transplants)

There are four other subspecialties the American Board of Pediatrics oversees that don’t have a similar subspecialty in adults. They are:

  • Adolescent medicine (focusing on children who’ve started puberty)
  • Child abuse pediatrics
  • Developmental-behavioral pediatrics
  • Neonatal-perinatal medicine (focusing on newborns and very young infants)

And several other medical boards oversee pediatric-specific subspecialties. Doctors who specialize in these areas may not be pediatricians, but do have extensive training in caring for children. These areas include:

  • Anesthesiology
  • Dermatology
  • Ear, nose and throat
  • Neurology
  • Pathology
  • Radiology
  • Rehabilitation medicine
  • Surgery
  • Urology

If your child needs to see a pediatric specialist, your child’s pediatrician can refer you when needed and may recommend specific providers.

Should a 17-year-old still go to a pediatrician?

Yes, a 17-year-old is still a child, so they should still see a pediatrician. But other types of pediatric care can continue after your child becomes a young adult, too.

In fact, there are cases where adults 21 or even older may continue to see their childhood pediatrician. These are usually adults with special healthcare needs. And pediatricians usually only agree to keep providing care to an adult if they have the ability to provide the proper care.

A note from Cleveland Clinic

Maybe your child has a mild fever and the sniffles, and you aren’t sure what to do about it. Or maybe they’re going through a particular phase, and you could use some advice on how to manage it.

Pediatricians don’t just care for your child. They also provide support for you. If you have questions or concerns about your child’s health, calling their pediatrician’s office is often your best first step. They can offer the guidance and reassurance you need as you navigate parenthood.
