15months
Preventive visit
Toddlerhood is taking shape—in movement, words, meals, and a growing sense of independence.
Use this guide to understand what the doctor will check, which tests or vaccines may be needed, what development looks like around 15 months, and how to support daily life at home.

Start here · Five useful questions
Fifteen months is a visit for the whole toddler—not a single test.
Second pillar
Lifestyle prevention
Every day: build family meals, language and active play, protect sleep and relationships, respond calmly to big feelings, and make exploration safer.
What the doctor does
The visit follows one simple arc: listen, check, protect, plan.
The exact order may change. These are the main parts most families can expect.
01
Listen
Your concerns, recent health, development, eating, sleep, behavior, childcare, family wellbeing, exposures, and safety.
02
Check
Weight, length, head size, growth over time, eyes, hearing responses, mouth and teeth, heart, hips, movement, gait, and a complete examination.
03
Protect
Developmental surveillance, oral prevention, follow-up of screening, and vaccines that are due after the full record is reviewed.
04
Plan
Family foods, milk and cups, teeth, language, active play, sleep, tantrums, childproofing, and the 18-month visit.
The toddler transition
The doctor follows how growth, skills, behavior, and daily life fit together.
This is mainly a surveillance visit. There is no routine formal developmental screen at 15 months, but your concerns and the doctor's observations still matter—and a concern should never wait for the next scheduled screen.
Prepare for the visit
A small list you can actually use.
0 of 5 ready
Tests and vaccines
The record matters more than the calendar alone.
At 15 months, many needs depend on what was already completed, the first-year feeding history, exposure risk, season, and local requirements.
Usually part of the visit
Development, eyes, hearing, mouth, and teeth
The doctor watches communication, movement, interaction, and gait; checks the eyes and response to sound; and assesses erupted teeth, brushing, fluoride, and the dental home.
Depends on history or risk
Blood tests, formal testing, and follow-up
Iron and lead testing, formal vision or hearing testing, blood pressure, tuberculosis testing, and repeat screening depend on earlier results, nutrition, exposure, symptoms, and program or local requirements.
Feeding history guides timing
Iron and anemia
Children mainly fed iron-fortified formula in the first year are generally screened at 15–18 months after changing to cow's milk. Earlier screening may already have been completed. Too much milk, limited iron-rich food, prematurity, or another risk can change the plan.
Why recommendations may sound different
Pediatric guidance recommends screening once within 9–18 months, with timing based on nutrition. A separate national evidence review found the evidence insufficient to recommend for or against routine screening in children without symptoms. Your child's feeding history and earlier results help guide the decision.
Earlier testing and local rules matter
Lead
A lead test may be needed when an earlier required test was missed, when housing or another exposure raises concern, or when insurance-program, state, or local rules require it. An abnormal finger-stick result needs confirmation with blood drawn from a vein.
Vaccines
Bring the complete record.
The doctor will use the current schedule, earlier products and doses, season, travel, and health history to decide what is actually due.
DTaP
The fourth dose falls within the 15–18-month window.
12–15-month vaccines
MMR, chickenpox, Hib, and pneumococcal doses may still be due if they were not completed earlier.
Hepatitis A and polio
A dose may be due depending on when the series began and what the record shows.
Influenza
Seasonal vaccination is reviewed each year.
Vaccine recommendations change over time. This guide intentionally does not replace the live schedule or your child's individualized vaccine review.
Development around 15 months
The doctor is watching a pattern—not grading a performance.
Children develop at different rates. These are selected abilities the visit may explore, not an exhaustive milestone checklist.
What the visit may explore
Communication
Uses one or two words besides mama or dada, looks toward a familiar object when it is named, and points to ask for help.
What the visit may explore
Movement and hands
Takes a few steps independently or is moving toward walking, and uses fingers to feed themself.
What the visit may explore
Connection
Shares attention through looking and pointing, responds to familiar people, and uses the caregiver as a secure base while exploring.
Speak up promptly
A concern does not need to wait until 18 months.
No pointing or other gestures
No response to name or sound
No words or meaningful attempts to communicate
Not pulling to stand, cruising, or moving toward walking
Very stiff, floppy, uneven, or one-sided movement
Loss of any skill your child previously had
What happens at the next visit
At 18 months, a standardized general developmental screen and an autism-specific screen are routinely scheduled. Screening can happen earlier whenever a caregiver or clinician has a concern.
Food, milk, and teeth
Family meals become practice for eating, learning, and connection.
Toddlers need structure and variety, while adults remain responsible for making food and the eating environment safe.
Eating and drinking
Offer family foods. Let appetite vary.
- Offer varied family foods and textures, including iron-rich foods, without pressure to finish.
- Whole cow's milk is the usual default from 12–24 months. The guide's source describes about 16–24 ounces a day.
- Use a cup, continue moving away from the bottle, serve water regularly, and keep juice to no more than 4 ounces a day.
- Avoid added sugar before age 2 and supervise meals closely to prevent choking.
When the milk plan changes
More than 24 ounces of milk a day can crowd out iron-rich foods. Lower-fat milk may be considered when growth, appetite, obesity risk, or family cardiovascular risk supports an individualized plan; it is not the routine default for every toddler.
Teeth and oral prevention
The adult still does the brushing.
- Brush twice daily with a smear—about a grain of rice—of fluoride toothpaste.
- Maintain a dental home and avoid a bottle in bed.
- Fluoride varnish begins after teeth erupt. Fluoride supplements depend on the fluoride level in the main drinking water.
Cut food into safe shapes and sizes. Avoid hard, round, or large choking hazards, and keep the child seated and supervised while eating.
Life at home · Contrada second pillar
Daily life is where toddler prevention happens.
Movement, language, sleep, relationships, and the physical environment shape health between visits.
Daily practice 01
Make room for active play
Offer safe floor and outdoor movement each day. Let the child walk, climb, carry, push, and explore with close supervision rather than spending long periods restrained.
Daily practice 02
Build language into ordinary life
Talk, read, sing, name objects and feelings, and respond to pointing and sounds. Shared attention is more useful than a formal lesson.
Daily practice 03
Use calm structure for big feelings
Emerging independence and tantrums can be normal. Keep routines predictable, offer simple choices, redirect when possible, and respond calmly.
Daily practice 04
Protect sleep
Aim for 11–14 total hours in 24 hours, including naps, with a consistent routine and the child learning to fall asleep in their own sleep space.
Daily practice 05
Childproof for a climber
Secure stairs, windows, furniture, medicines, cleaners, hot liquids, water, and firearms. Stay within reach around water and keep the car seat rear-facing to its stated limits.
Daily practice 06
Reduce harmful exposure
Keep the home and car free of tobacco smoke, nicotine, vaping aerosol, and cannabis exposure. Avoid screen media other than live video chatting at this age.
Lead: older or renovated housing, imported goods, and take-home workplace exposure can change testing and prevention needs.
Poisoning: keep the U.S. Poison Control number available: 1-800-222-1222.
When to get help
Know what can wait—and what should not.
This is a focused guide, not a complete emergency manual. Contact your child's clinician whenever something feels seriously wrong.
Discuss with the clinician
Concerns about words, gestures, walking, hearing, vision, sleep, tantrums, picky eating with poor growth, too much milk or juice, persistent bottle use, or caregiver stress.
Seek prompt assessment
Loss of a skill, growth faltering, persistent feeding trouble, unusual paleness or fatigue, tooth decay, possible lead exposure, or a lasting concern about eyes, hearing, balance, or gait.
Emergency care
Serious breathing difficulty, choking, a severe allergic reaction, a seizure, difficulty waking or responding, a major injury, burn or drowning event, or suspected poisoning.
Looking ahead
Next routine visit: 18 months.
The next visit continues growth, development, feeding, teeth, behavior, safety, and vaccine review—with two formal developmental screens added.
The immediate next step
The 18-month visit
A standardized general developmental screen and an autism-specific screen are routinely scheduled, alongside the usual health, growth, oral-health, safety, lifestyle, and vaccine review.
Until then
Keep watching the whole child.
Continue family foods, cup use, brushing, language-rich play, predictable routines, safe movement, and close supervision. Bring up a concern or lost skill before the next routine visit.
