What Does a Pediatrician Do?

These doctors are trained to take care of children from birth to adulthood

A pediatrician is a healthcare provider who specializes in the care of children and adolescents, providing vaccines for the smallest of babies or caring for a college student diagnosed with an eating disorder. You also may encounter nurse practitioners who specialize in pediatric care.

With additional training, some pediatricians focus on a specific area of care, such as cardiology or genetics. Others may have training in the care of LGBTQ+ youth, or with developmental health issues like autism.

This article explains the role of a pediatrician in health care for children, teens, and young adults. It will help you to learn more about their training, specialties, and the services that pediatricians offer.

What Is a Pediatrician?

Pediatricians focus on the health of infants and children, providing wellness visits and screenings or treating common illnesses like ear infection. They also assess and monitor a child's development, providing referrals to other specialists in the event of a serious emerging health condition, social or behavioral challenges, or mental health concerns.

Some pediatricians are certified in adolescent and young adult medicine, and care for the needs of people up to age 25. These providers may treat substance use disorders, reproductive health concerns, and more.

What Do Pediatricians Do?

The American Academy of Pediatrics lists dozens of areas of expertise for pediatric healthcare providers. The care and services for children and young people include:

Pediatricians can treat a range of conditions, from common childhood illnesses like chickenpox to minor injuries that require stitches or splinting. They may refer you to specialists for additional care, or practice a specialty themselves (in treating allergies, for example).

Pediatrician Subspecialties

There are many types of pediatricians. There are general pediatricians who practice primary care, taking care of the general needs of children, and there are others who specialize in certain areas, such as:

Adolescent Medicine

Adolescents face tremendous social and academic pressures, as well as potentially life-threatening illnesses, habits, and behaviors. Adolescent health specialists are trained to help teens and young adults between the ages of 10 and 25 with their complex physical, behavioral, and emotional health care needs—from physical exams and immunizations to reproductive and mental health care.

Pediatric Cardiology

If your pediatrician has a question about your child’s heart, he or she may refer your child to a pediatric cardiologist, a healthcare provider who specializes in diagnosing and treating heart problems in children.

Child Abuse Pediatrics

These healthcare providers have special training, experience, and skills in evaluating children who may be victims of some type of abuse or neglect. 

Pediatric Critical Care Medicine

A hospital-based pediatric critical care specialist is called on to provide the special care your child might need if he or she is in an unstable critical condition due to a serious illness or injury.

Developmental-Behavioral Pediatrics

These specialists possess training and experience to consider the medical and psychosocial aspects of children’s and adolescents’ developmental and behavioral problems. These include problems in a full range of pediatric chronic illnesses and disabling conditions, such as cerebral palsy.

Be sure to tell your healthcare provider about a child’s behavior even if they don't ask. They typically have a lot of knowledge about mental health and behavioral issues, and can refer you to specialists and community resources after evaluating whether your child can benefit from additional servicces.

Pediatric Emergency Medicine

These specialists focus on the care of the acutely ill or injured child in an emergency department.

Pediatric Endocrinology

If your child has problems with growth, pubertydiabetes, or other disorders related to the hormones and the glands that produce them, they may be referred to a pediatric endocrinologist.

Pediatric Gastroenterology

These specialists care for children and adolescents who have digestive difficulties. A gastroenterologist also may have specific areas of expertise, such as liver disease.

Pediatric Hematology-Oncology

If your child is affected with blood disorders and cancer they may see a pediatric hematologist-oncologist.

Pediatric Hospital Medicine

Pediatric hospitalists work primarily in a hospital. They care for children throughout the hospital, including the pediatric acute care areas, the newborn nursery, the emergency department, labor and delivery, and sometimes the neonatal (NICU) or pediatric intensive care units (PICU).

Pediatric Infectious Diseases

These specialists evaluate and treat children with acquired or congenital disorders of the immune system, including those caused by bacteria, a fungus, a parasite, or other rare infection.

Neonatal-Perinatal Medicine

Premature and high-risk babies are often cared for by these specialists.

Pediatric Nephrology

A pediatric nephrologist specializes in care for children with various kidney diseases.

Pediatric Pulmonology

If your child has breathing or lung problems, he or she may see a pediatric pulmonologist.

Pediatric Rheumatology

These specialists care for children with autoimmune diseases, or diseases where the immune system attacks the healthy cells of the body. Rheumatic diseases include fevers, joint pains, rashes, and involvement of the internal organs.

Pediatrician Training and Certification

After graduating from medical school, pediatricians take special courses solely in pediatrics for three or more years. This is called residency. This training exposes them to the various clinical rotations in different pediatric sub-specialties, like endocrinology or emergency medicine.

After completing residency training, the pediatrician is eligible to take a written exam given by the American Board of Pediatrics. A board-certified pediatrician can add the designation Fellow of the American Academy of Pediatrics (FAAP) after their names.

Pediatricians who subspecialize must also meet the training requirements specific to each of those subspecialties. To maintain their certification, pediatricians and pediatric specialists must also work to stay up to date with the most current medical knowledge over the course of time that they practice medicine.

How Long Does It Take to Become a Pediatrician?

At least 11 years of education is required to become a pediatrician. This includes four years of college, four years of medical school, and then at least three years of a pediatric residency. A pediatrician may then spend additional years training on a specialty like cardiology or endocrinology.

Pediatrician Appointment Tips

Patient appointments may be just one small part of a pediatrician’s job, but they'll have a big impact on your life. Use these tips to make the visit go as smoothly as possible:

  • Have your child's medical history and medications on hand.
  • Prioritize your questions and write them down ahead of time.
  • Get any training you need on how to use new equipment or medication.
  • Tell the pediatrician if you need other resources, like a social worker.

You can try scheduling appointments early in the day to avoid long wait times. It also may help to bring your own toys, snacks, diapers, and other items to make the visit easier for your child.

When to Make an Appointment With a Pediatrician

Your child or teen may need to see a pediatrician for a wide range of reasons. It also can depend on the age of the child. A fever of 100.4 F in a newborn should be seen by a healthcare provider, for example, but that threshold is 102.2 F in babies between three months and one year.

Some of the more common reasons for calling your pediatrician can include:

Apart from illness, your child may experience a traumatic injury and need to be seen. Other reasons can include developmental concerns (for example, speech and talking skills that aren't neurotypical) and behavioral concerns (like oppositional behavior or conduct problems).

How to Choose a Pediatrician

Choose a trusted healthcare provider to care for your child. Ask friends and family for recommendations, but check the provider's credentials and make a thoughtful decision yourself.

You also can check with professional organizations. You'll need to confirm that a pediatrician accepts your health insurance or has policies that are not a barrier to care.

When choosing a pediatrician, make sure you're comfortable with how they meet your child's needs (for example, LGBTQ+ youth concerns) or that they're the right specialty for a specific condition.

Summary

A pediatrician provides health care to children and teens, including adolescent and young adult specialists who care for people up to the age of 25. They provide well visits and other routine care, including immunizations and childhood health screenings, as well as treating illness and injury.

A pediatrician also may be a specialist in a certain field of medicine, such as heart or cancer care. You may encounter nurse practitioners and other providers who specialize in pediatric care, too. Resources and referrals are available to help you choose the right pediatrician for your child.
