Childhood health screenings help you understand how your child is growing, learning, seeing, hearing, and feeling. They also give your pediatrician a chance to spot concerns early : before a small issue becomes harder to manage.

A screening is not a prediction. It is a simple check or set of questions that helps your child’s care team decide whether more support may be useful.

This guide explains common pediatric care milestones from birth through adolescence. Use it to prepare for visits, keep track of questions, and find the right provider when your family needs one.

Important: Screening schedules can vary based on your child’s health, family history, risk factors, location, and pediatrician’s guidance. This article supports: not replaces: personal medical advice.

Childhood Health Screenings, Explained

Regular well-child visits are the foundation of preventive pediatric care. The American Academy of Pediatrics recommends visits throughout infancy, childhood, and adolescence. These visits are not only for sick days.

During a well-child visit, your child’s provider may:

• Measure height, weight, and growth patterns.
• Review development, learning, sleep, eating, and behavior.
• Check hearing, vision, heart, lungs, skin, and movement.
• Review vaccines and preventive care.
• Ask about safety at home, school, sports, and online.
• Discuss emotional health and family concerns.
• Complete age-based screenings.
• Answer your questions.

The goal is continuity : keeping a steady relationship with a pediatrician who knows your child over time. The AAP describes well-child care as a team approach between families and healthcare professionals.

Birth to 12 Months: Building the Foundation

Newborns receive several important checks soon after birth. These may include a physical examination, newborn blood screening, hearing screening, and screening for jaundice. Your baby’s care team explains which tests are completed before leaving the hospital and which need follow-up.

The first year also includes frequent well-child visits. A common schedule includes visits during the first week, then around 1, 2, 4, 6, 9, and 12 months. Your pediatrician may recommend additional visits if your baby was born early, has a health condition, or needs closer monitoring.

Growth and feeding checks

At infant visits, the provider tracks growth over time rather than focusing on one measurement. You may discuss:

• Feeding and appetite.
• Breastfeeding or formula concerns.
• Introduction of solid foods.
• Sleep routines.
• Spitting up, constipation, or other common concerns.
• Vitamin or supplement needs.
• Safe sleep.
• Car seat use.
• Home safety.

Growth patterns differ from child to child. A single number does not tell the whole story. Your pediatrician looks at the overall pattern and listens to what you are seeing at home.

Developmental monitoring

Developmental monitoring happens throughout childhood. Your provider may ask whether your baby is reaching expected movement, communication, learning, and social milestones.

The CDC’s Learn the Signs. Act Early. program offers milestone information for children from infancy through age 5. These checklists can help you notice what your child is doing and prepare questions for the next visit.

Formal developmental screening is commonly recommended at 9 months, 18 months, and 30 months. The screening usually involves a parent questionnaire or a short, age-appropriate activity. It does not determine a diagnosis by itself.

Hearing and vision

Your baby’s hearing is usually screened soon after birth. If the result needs follow-up, schedule that evaluation promptly. Tell your pediatrician if your baby does not respond to sounds, turns toward voices inconsistently, or seems to have difficulty seeing objects or faces.

Providers also watch eye movement and alignment during infant visits. Early concerns may require a referral to an eye specialist.

Lead and anemia screening

Lead exposure can affect a child’s health and development. Your provider may ask about risk factors such as older housing, renovation, imported products, or contaminated soil. Blood testing is recommended for children with risk factors and in areas where local rules or public health guidance call for it.

Anemia screening often takes place around 9 to 12 months. The provider may recommend testing sooner or later based on diet, prematurity, chronic illness, or other risk factors.

12 to 30 Months: Watching Development Closely

The toddler years bring fast changes. Your child may begin using more words, walking and running, feeding themselves, playing near or with others, and showing strong preferences.

Well-child visits around 12, 15, 18, 24, and 30 months help your pediatrician follow these changes. They also create space for questions about sleep, picky eating, behavior, toilet learning, and safety.

Autism screening

Routine autism-specific screening is commonly recommended at 18 and 24 months. Your pediatrician may also screen at another age if you or the care team notice concerns.

Autism screening looks at communication, social interaction, play, and behavior. It is a starting point for understanding whether a child may benefit from a fuller evaluation or early support.

Ask for guidance if your child:

• Stops using a skill they once had.
• Does not respond to their name as expected.
• Has few gestures or words for their age.
• Does not point to share interest.
• Avoids interaction much of the time.
• Repeats movements or routines that interfere with daily life.
• Shows a sudden or significant change in behavior.

Do not wait for the next scheduled visit if you are worried. You know your child best, and raising a concern early is helpful.

Dental care and fluoride

A child’s first dental visit is generally recommended after the first tooth appears or by around the first birthday. Primary care and dental providers may discuss brushing, fluoride, bottle use, thumb-sucking, and early tooth decay.

The AAP notes that fluoride varnish may be applied once teeth are present, with timing based on risk. Ask your pediatrician or dentist what fits your child.

Ages 3 to 5: Preparing for Preschool and School

Annual well-child visits become the usual pattern during the preschool years. Your provider continues tracking growth and development while adding more formal hearing, vision, blood pressure, and school-readiness checks.

Vision screening

Vision screening can begin around age 3 when a child can participate. The U.S. Preventive Services Task Force recommends at least one vision screening between ages 3 and 5 to identify problems that could affect sight or eye development.

A child may not say that they cannot see well. Watch for signs such as:

• Squinting or sitting very close to screens.
• Tilting the head to look at objects.
• Covering one eye.
• Frequent eye rubbing.
• Trouble tracking objects.
• Headaches after reading or schoolwork.
• Avoiding drawing, books, or close-up tasks.

If a screening result is unclear, your child may need a repeat test or a complete eye examination.

Hearing screening

Many pediatric offices begin routine hearing checks around age 4. Hearing may also be screened through school or community programs.

Hearing can affect speech, learning, attention, and classroom participation. Tell the provider if your child often says “what,” watches television loudly, misunderstands directions, or seems not to hear from another room.

Blood pressure and risk-based tests

Blood pressure screening commonly begins at age 3 during routine visits. The cuff must fit your child correctly, and an unusual result may need to be repeated.

Your provider may also ask about risks for high cholesterol, lead exposure, tuberculosis, and other concerns. Not every child needs every blood test. The decision depends on history and risk.

Social, emotional, and behavior checks

Preschool visits are a useful time to discuss:

• Separation worries.
• Strong tantrums or aggression.
• Trouble sleeping.
• Social interaction.
• Speech or learning concerns.
• Daycare or preschool adjustment.
• Family stress.
• Caregiver emotional health.

These conversations are part of whole-child care. They are not a judgment about your parenting.

Ages 6 to 10: Supporting Learning and Everyday Health

School-age visits continue each year. Your child may appear healthy while still needing preventive care. Regular checkups help you stay current with vaccines, growth monitoring, oral health, vision, hearing, and emotional well-being.

The provider may ask about:

• School performance.
• Reading and learning.
• Friendships and bullying.
• Physical activity.
• Nutrition and body image.
• Sleep.
• Screen use.
• Asthma, allergies, headaches, stomach pain, or other recurring symptoms.
• Sports participation and injury prevention.

Some children need additional support at school. If your child is struggling to read, focus, hear instructions, see the board, or keep up physically, tell both the teacher and pediatrician.

Your pediatrician can help coordinate next steps, which may include hearing or vision testing, learning support, behavioral evaluation, or another specialist.

Ages 11 to 21: Preventive Care for Adolescents

Adolescent visits protect more than physical health. They give young people a regular place to discuss stress, friendships, mood, sleep, substance use, relationships, safety, and sexual health.

Mental and emotional health

Routine adolescent care may include screening for depression, anxiety, suicide risk, and other emotional concerns. Your provider may speak with your teen alone for part of the visit. This helps create a private, honest space while keeping safety at the center.

Seek help sooner if your teen shows:

• A major change in mood or behavior.
• Withdrawal from friends or family.
• Loss of interest in activities.
• Sudden changes in sleep or eating.
• Falling grades.
• Frequent unexplained physical complaints.
• Hopelessness or comments about death.

If your child may be in immediate danger, contact emergency services or a crisis resource in your area.

Physical health and risk checks

Adolescent preventive care may include:

• Blood pressure checks.
• Growth and body mass index review.
• Vaccine updates.
• Hearing risk assessment.
• Cholesterol screening at recommended ages or when risk factors are present.
• HIV and sexually transmitted infection screening based on age, activity, and risk.
• Substance use questions.
• Sports and injury prevention counseling.
• Confidential reproductive and sexual health discussions.

Ask your provider how confidentiality works in your state. Parents and teens can both benefit from knowing what information is private and what concerns require adult involvement for safety.

A Simple Childhood Screening Checklist

Use this checklist before your child’s next visit:

1. Book the well-child visit. Annual care matters even when your child feels well.
2. Write down changes. Note changes in sleep, eating, mood, school, movement, speech, hearing, or vision.
3. Bring vaccine and school forms. Include records from other clinics.
4. Share family history. Mention new diagnoses in parents, siblings, or close relatives.
5. Ask about due screenings. Say, “Which screenings are recommended at this age?”
6. Ask about referrals. If a result is unclear, learn the next step and timing.
7. Confirm follow-up. Before leaving, ask who will call with results and when.
8. Keep dental care separate but connected. A pediatrician and dentist support different parts of your child’s health.

When to Call Before the Next Checkup

Do not wait for a routine visit if you have a serious concern. Contact your child’s healthcare provider about sudden changes, breathing problems, severe pain, dehydration, unusual sleepiness, significant injury, or a high fever in a young infant.

For developmental concerns, earlier conversations are useful. You do not need to prove that something is wrong before calling. Share what you notice, how long it has been happening, and how it affects daily life.

A pediatrician can help you decide whether your child needs an urgent visit, a routine appointment, a screening, or a referral.

The Bottom Line

Childhood health screenings are milestones for staying connected to your child’s health. They cover more than height and weight. They help track development, hearing, vision, learning, emotional health, oral health, and safety from birth through adolescence.

Choosing a pediatrician you trust makes these visits easier. Look for a provider who listens, explains next steps clearly, accepts your insurance when possible, and offers care that fits your family’s needs.
