Childhood health checks: what to expect from birth onward
Childhood health checks are a short series of screens, exams and vaccines that begin with a newborn blood spot test at 24 to 48 hours in the US (5 days in the UK) and continue through infancy and childhood. Most are quick, and most happen at visits you would be going to anyway.
If you have a new baby or a young daughter, the list of appointments can look long, and it's common to wonder what each one is for. Each check has one narrow job: to notice something small while it is still simple to help with. You don't need to memorize any of it, because your pediatrician's office keeps track, and you're always welcome to ask what is next.
What are childhood health checks, and where do they happen?
Childhood health checks are the routine screens, exams and vaccines offered from birth, and most happen at regular well-child visits rather than separate appointments. Timings on this page follow US guidance from the American Academy of Pediatrics Bright Futures schedule and the CDC. In the UK you are more likely to hear about a health visitor or GP, and the blood spot test is often called the heel prick test.
The first year holds the most visits, which can feel like a lot when you are short on sleep, but each has a small, specific purpose. For the wider picture of how a girl's body grows, see what changes in childhood. Feeding questions come up at almost every early visit, and breastfeeding and feeding in the first year covers them in detail.
Vaccines are where the two countries drift furthest apart: the US follows the CDC schedule, while the UK follows the UKHSA routine immunisation schedule, where the timing differs. Many families find it useful to keep their own country's schedule beside the baby's record book and tick off each visit.
Check, when, what to look for
| Check | When | What to look for | Guidance by country |
|---|---|---|---|
| Newborn physical exam | Before leaving the hospital, then at well-baby visits at 3 to 5 days and at 1, 2, 4, 6, 9 and 12 months. | Eyes, heart and hips.The hips are looked at again at the early well-baby visits, not only at birth. | UK: the NHS offers it within 72 hours of birth and again at 6 to 8 weeks. |
| Newborn blood spot test | At 24 to 48 hours after birth. | Sickle cell disease, cystic fibrosis and the other core conditions on the panel, about 35 in the US.It's worth asking at the hospital how and when results will reach you. | UK: at 5 days; 9 conditions. |
| Newborn hearing test | Before leaving the hospital, or by 1 month. | Hearing in both ears, with a fuller evaluation arranged if the screen needs one.A check is available at any age if hearing or speech is a worry. | – |
| Vaccinations | From birth, then at 2, 4, 6 and 12 to 18 months and at 4 to 6 years, with a yearly flu vaccine from 6 months. | Protection against measles, whooping cough and meningitis.A written record of which vaccines are done is easy to ask for at any visit. | UK: the UKHSA routine immunisation schedule differs in timing. |
| Developmental screening | At 9, 18 and 30 months, with autism screening at 18 and 24 months. | How your child is moving, communicating, playing and learning.Examples you've noticed, such as new words, favorite games or things your child avoids, help the screening paint a fuller picture. | – |
| Growth | At every well-child visit. | Weight and height plotted on a growth chart.Your child's own line over time tells more than any single reading. | UK: centile charts. |
| Vision | From age 3 at well-child visits, then regularly. | Crossed eyes, lazy eye and nearsightedness.Squinting or head tilting is a reason to see an eye doctor sooner. | – |
| Dentist | By the first birthday, then about every 6 months. | Healthy teeth and gums as the first teeth come through.Fluoride varnish is offered from the first tooth and at well-child visits. | – |
| Early puberty signs | Not a scheduled check; something to watch for through childhood. | Breast development before 8, or periods before 10.A pediatrician visit is the next step. | – |
| Wellbeing | Any time, with no set age. | Changes in sleep, appetite, behavior or friendships.Jotting down roughly when a change began gives the school or the pediatrician something concrete to work with. | – |
What do health checks look for after the first birthday?
After the first birthday, the focus moves from newborn screening to how your child is growing, seeing, developing and feeling. Visits are further apart, and more of what gets noticed comes from you, because you see your child every day.
Weight and height are plotted at every well-child visit, and what matters is the line your child follows over time. A shift across percentile lines (centile lines in the UK) is a reason for a conversation, not a verdict, and the aim is steady growth and a strong, healthy body.
Developmental screening is a structured look at skills that children pick up at different speeds, and it exists to offer support early. If something you've noticed doesn't come up, it's fine to raise it yourself. Dental care starts earlier than most people expect, with fluoride varnish from the first tooth.
Wellbeing is the easiest check to overlook, because nothing on the calendar prompts it. Once school starts, teachers see a side of your daughter that you may not, which makes them useful partners. Some concerns, such as pain on peeing, don't need to wait for a scheduled visit, and a call to your pediatrician's office (your GP in the UK) is a sensible way to ask. For the years after this one, health checks in puberty picks up where this page stops, and health checks for women lays out every life stage in one place.
Which childhood checks matter most for girls?
Two checks deserve a little extra attention for girls: the newborn hip exam and watching for early signs of puberty. Neither is a reason to worry in advance; they are simply where being a girl is relevant to what the checks look for.
Bright Futures notes that hip problems are more common in girls and in breech babies. If your daughter was breech, it's worth mentioning at her early visits so it is on her record.
Puberty that starts sooner than expected is also more common in girls, and it is treatable. The ages in the table are a prompt to ask, not a diagnosis, and our page on early puberty explains what the signs look like and what happens next.

Facts
Common questions
What happens if my child has missed a check or a vaccine?
Missing a visit is common, and it can be put right. The CDC's 2025 schedule says children who are behind should catch up as early as possible, and it covers ages 18 and under. A good place to start is a call to your pediatrician's office to ask what is outstanding. In the UK, your GP practice or health visitor can do the same.
What happens if my baby doesn't pass the newborn hearing test?
The next step is a fuller hearing evaluation, not a diagnosis. The CDC's benchmarks aim for a diagnostic evaluation by 3 months and, if hearing loss is confirmed, early intervention by 6 months. If no follow-up has been arranged before you go home, it's worth asking who will book it.
Why does vision screening start at age 3 and not earlier?
The US Preventive Services Task Force (2017) recommends at least one vision screen at ages 3 to 5 to detect amblyopia, the medical name for lazy eye, and found the evidence insufficient for children under 3. If you notice squinting or head tilting at any age, an eye doctor can see your child sooner.
Which growth chart will my child be measured on?
The CDC advises WHO growth standards from birth to 2 years, then CDC growth charts from 2 to 20 years, so the chart changes at the 2-year visit. You are welcome to ask to see the chart and have the line explained, including where your child sits and how it has moved since the last time.
Who do I ask if I'm worried between visits?
There's no need to wait for the next scheduled visit. Your pediatrician's office, or your GP or health visitor in the UK, can see your child for a specific concern, such as hearing, speech or a change in growth. Noting what you've seen, when it started and how often it happens makes a short appointment far more useful.
Next steps
A good place to start is finding out which check is next for your child and adding it to your calendar. If you keep a record of visits and vaccines, bringing it along can make each appointment easier. If something on the red flag list sounds familiar, a call now is a sensible step and need not wait for the next routine visit. Take from this page whatever fits your daughter and your family, because health checks are not one size fits all.

- Pain on peeing
- Any worry about hearing or speech, at any age
- Severe eczema or a known food allergy before introducing egg or peanut: talk to the pediatrician first
