6months
Preventive visit
A visit for a baby entering a more active—and more edible—world.
Use this guide to understand what the doctor will check, which protections may be due, how to approach first foods, and what changes at home as movement and curiosity grow.

Start here · Five useful questions
This visit is where several parts of infancy begin to change at once.
Second pillar
Lifestyle prevention
Every day: build a safe first-food routine, protect sleep, make room for movement and connection, care for new teeth, support caregivers, and prepare the home for mobility.
What the doctor does
The visit follows one simple arc: listen, check, protect, plan.
The exact order may change. These are the major parts a family can expect.
01
Listen
Your concerns, feeding, sleep, development, childcare, family wellbeing, exposures, and safety.
02
Check
Weight, length, head size, growth pattern, vision and hearing responses, movement, supported sitting, and a complete examination.
03
Protect
Vaccines due now, caregiver mood and social-needs screening, oral-health risk assessment, and early attention to any concern.
04
Plan
First foods, vitamin D and iron, teeth, safe sleep, mobility, home safety, and the 9-month visit.
Growth and examination
The doctor is following a pattern, not grading one day.
Weight, length, and head size are plotted over time. The examination also follows vision, hearing, head shape, mouth and teeth, heart, abdomen, hips, skin, muscle tone, movement, and growing trunk control.
What if something worries me?
Bring it up now. A concern about growth, feeding, interaction, hearing, vision, movement, or a lost skill should be assessed without waiting for the formal 9-month developmental screen.
Prepare for the visit
A small list you can actually use.

Vaccines and safety
Some vaccines are routine. Others depend on the record or the season.
Separating these groups makes it easier to see what most babies receive and what needs an individual decision.
Usually given at this visit
DTaP
Protects against diphtheria, tetanus, and whooping cough.
Injection · third dose
Polio
Protects against polio and paralysis.
Injection · usually third dose
Pneumococcal
Protects against serious pneumococcal infections.
Injection · third dose
One visit
Vaccines that are due can be given together.
There is no benefit to separating the indicated vaccines. The clinician should first check age, earlier doses, products, season, and health history.
The product decides
Hib and rotavirus
A third Hib dose is needed only with certain products. A third oral rotavirus dose is needed only for the three-dose brand, and every rotavirus dose must be completed by 8 months.
Age and history decide
Hepatitis B
The final dose may be given between 6 and 18 months, but it cannot count as the final dose before 24 weeks of age. Combination vaccines may affect what appears on the record.
Seasonal from 6 months
Influenza
Influenza vaccination begins at 6 months. During the first influenza season, most babies need two separate doses at least four weeks apart.
Recommendations differ
COVID-19 vaccination
Current pediatric and federal recommendations do not fully agree: one recommends vaccination routinely for all children 6–23 months, while the other uses an individual family-clinician decision. Ask which current guidance applies.
Season and prior protection decide
RSV protection
RSV antibody protection is not automatically repeated at this visit. It may be due when a baby younger than 8 months is entering the first RSV season and was not already protected during pregnancy or by an earlier antibody dose.
Usually short-lived
What is common
Soreness, redness or swelling where a shot was given, fever, fussiness, sleepiness, or lower appetite may begin during the next day or two and usually resolve.
Know the uncommon signs
When a reaction is urgent
Get emergency help for breathing difficulty, facial or mouth swelling, collapse, seizure, or a baby who is limp or hard to wake.
After rotavirus vaccine
Severe waves of crying with the legs pulled toward the chest, repeated vomiting, bloody or mucus-containing stool, pallor, or unusual sleepiness may signal an intestinal blockage and need emergency evaluation.
Feeding and first foods
Milk remains central. Food begins as practice, variety, and nourishment.
For most babies, complementary foods begin around 6 months when developmentally ready. The goal is a safe beginning—not a perfect menu.
Begin with what matters
Iron-rich foods, safe textures, and close supervision.
Breast milk or iron-fortified formula remains the major source of nutrition while complementary foods gradually expand.
Prioritize iron and zinc
Offer developmentally safe iron- and zinc-rich foods such as fortified cereals, meats, or legumes, alongside a variety of nutrient-dense foods.
Continue vitamin D
Give 400 IU each day when the baby is breastfed, partly breastfed, or drinks less than 28 ounces of formula daily.
Clarify the iron plan
For a baby receiving mostly human milk, review whether iron supplementation continues until food provides enough iron.
Prevent choking
Seat the baby upright, supervise every feeding, adjust texture, and avoid hard, round, or small foods such as nuts, whole grapes, popcorn, raw hard vegetables, and hot-dog rounds.
Risk changes the plan
Introduce allergens thoughtfully
Do not deliberately delay peanut, egg, and other allergenic foods once a baby is ready. Severe eczema or egg allergy calls for an individual peanut-introduction plan.
Simple boundaries
Keep these out for now
No honey, juice, sugar-sweetened drinks, cow's milk, or plant-based milk as a drink before 12 months. Do not prop bottles or put the baby to bed with one.
Growth and development
At 6 months, learning is visible in sounds, hands, faces, and movement.
These are abilities many babies show around this age—not a performance your baby has to give during the visit.
Connection
Knows familiar people, laughs, enjoys looking in a mirror, and joins face-to-face interaction.
Communication
Takes turns making sounds, blows raspberries, and begins consonant sounds.
Hands and curiosity
Reaches, grasps, transfers objects between hands, and brings objects to the mouth to explore.
Movement
Sits with support, leans on the hands while sitting, may roll, and pushes up on straight arms during tummy time.
Not expected of every baby
Still emerging
Sitting alone, rocking on hands and knees, early crawling preparation, and wariness of unfamiliar people may begin over the coming months.
But concerns do not wait
No formal screen today
A standardized developmental screen is usually scheduled at 9 months. If you or the doctor has a concern now, screening and referral can happen now.
Signs to discuss with the doctor
Little interest in social interaction, avoiding eye contact, smiling or vocalizing infrequently, no back-and-forth engagement, not reaching for objects, not bringing objects to the mouth, or losing a skill.
Teeth and oral health
Oral prevention begins before there is much to brush.
At 6 months, the doctor begins a routine oral-health risk assessment. Tooth-specific care begins as soon as the first tooth appears.
As soon as it erupts
Brush the first tooth
Use a soft brush and a smear—about a grain of rice—of fluoridated toothpaste.
After tooth eruption
Fluoride varnish
Fluoride varnish is recommended once primary teeth appear. Timing may be more frequent when cavity risk is high and continues until a dental home is established.
Supplement only when needed
Check the water
Fluoride supplements depend on the fluoride level in the baby's primary drinking water. Do not add one without an individual recommendation.
Life at home · Contrada second pillar
Curiosity grows faster than the room can prepare itself.
At 6 months, daily prevention means making food, sleep, movement, relationships, and the environment ready for a more active baby.
Daily practice 01
Protect every sleep
Place the baby on the back on a firm, flat, non-inclined surface. Room-share without bed-sharing and keep soft items, toys, and inclined sleepers out.
Daily practice 02
Make room to move
Use supervised tummy time, floor play, reaching, rolling, and supported sitting. Skip baby walkers.
Daily practice 03
Read, talk, and answer
Make sounds back and forth, read, sing, smile, and respond to the baby’s cues. Keep screens minimal during infancy.
Daily practice 04
Prepare for mobility
Install stair gates and window guards, prevent falls, secure medicines and chemicals, reduce burn hazards, and supervise closely near water.
Daily practice 05
Support the caregivers
Caregiver mood, fatigue, relationships, childcare, practical support, and access to food and housing are part of the baby’s health.
Daily practice 06
Reduce exposures
Keep the home and car free of tobacco, nicotine, vaping, and smoke. Address lead sources and substance use that could impair supervision or safe sleep.
When to get help
Know the difference between a question, a prompt assessment, and an emergency.
This is a focused guide, not a complete emergency manual. Trust a serious concern and contact your baby's clinician.
Contact the clinician
Fever, feeding, or fewer wet diapers
Call for a temperature of 100.4°F (38°C) or higher, feeding refusal, fewer wet diapers, persistent fussiness, or ongoing vomiting or diarrhea.
Prompt assessment
Markedly decreased urine, no tears, dry mouth, sunken eyes or soft spot, lethargy, persistent or rising fever, or increasing work of breathing.
Emergency now
Grunting, chest pulling in, pauses in breathing, blue lips or face, seizure, choking, collapse, unresponsiveness, severe allergic-reaction signs, or serious injury.
Developmental changes that should not wait
Contact the doctor for a lost skill or a new concern about interaction, eye contact, sounds, reaching, movement, hearing, or vision.
Looking ahead
Next routine visit: 9 months.
The next visit brings a formal developmental screen and another look at growth, feeding, movement, teeth, safety, and family wellbeing.
At 9 months
Development gets a more formal check.
A standardized developmental screen becomes routine. Bring forward anything you have noticed about movement, sounds, interaction, feeding, sleep, or lost skills.
Before then
Food expands. Mobility accelerates.
Continue safe first foods, finish a second influenza dose when required, protect sleep, care for teeth, and prepare the home for crawling and pulling to stand.
