Medical Care and Your 1- to 3-Month-Old

During these early months, you might have many questions about your baby's health. Most doctors have phone hours when parents can call with routine questions. Don't hesitate to call with your concerns, no matter how minor they might seem.

Of course, if you think your baby could have an illness, don't wait for phone hours — call your doctor right away. As in the newborn period, illness at this age needs attention right away.

How often you see the doctor in the first 2 months will depend on your baby's health, but most infants are seen at 1 month and again at 2 months for routine care.

Babies are checked for growth, development, and feeding, among other things. These regular checkups also let your doctor follow up on any concerns from earlier checkups and are a chance for you to ask questions.

What Happens at the Office Visit

During these early months, your doctor will check your baby's progress and growth. Common parts of a checkup include:

• weight, length, and head circumference measurements that are plotted on your baby's growth chart
• a physical exam with special attention to any previous problems
• checking development (for example, head control, cooing, and smiling)
• questions about how you're doing with your baby
• advice about feeding and nutrition
• what to expect during the coming months, including a discussion about safety precautions
• vaccines during some visits

Bring up any questions you have, and write down the answers or specific instructions the doctor gives you. At home, update your baby's medical record, tracking growth and any problems or illnesses.

Vaccines

At 1–2 months old, your baby should get the second dose of the hepatitis B (HepB) vaccine or their first dose if they didn't get it in the hospital within 24 hours of birth.

At 2 months, your baby will get other vaccines:

• DTaP (diphtheria, tetanus, acellular pertussis) vaccine
• Hib (Haemophilus influenzae type b) vaccine
• IPV (polio vaccine)
• PCV (pneumococcal vaccine)
• RV (rotavirus vaccine)

Some babies also get an RSV antibody shot, usually those born just before or during RSV season or whose mother didn't get an RSV vaccine during pregnancy.

Babies at high risk for meningococcal disease, which can lead to bacterial meningitis and other serious conditions, may get the meningococcal vaccine. (Otherwise, kids usually get the meningococcal vaccine when they're 11–12 years old.)

Vaccines protect against serious childhood illnesses. Like any other medicine, vaccines may cause reactions (usually mild), such as fever or irritability. Talk about side effects with your doctor, and ask when to call if you have a concern.

When Should I Call the Doctor?

Some common medical problems at this age may need a doctor's attention, including:

• diarrhea and vomiting, which could be caused by an infection and put your infant at risk for dehydration
• rashes, which are common in infants. Some may not seem to bother your baby, but skin conditions like eczema can cause dry, itchy skin. Your doctor can recommend lotions, creams, and soaps to try.
  
• upper respiratory tract infections (including colds), which affect infants just like the rest of us. Babies can't blow their own noses, so you may need to help clear mucus with a rubber bulb aspirator. Don't give your baby any medicines without checking first with your doctor. Call the doctor's office right away if your baby has trouble breathing, refuses to eat, has a rectal temperature above 100.4°F (38°C), or is very cranky or sleepy.

You know your baby best. Call the doctor's office about any health or behavior concerns.
