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

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

Of course, if you suspect illness, don't wait for phone hours — call your doctor immediately. As in the newborn period, illness at this age requires immediate attention.

You will most likely visit your doctor with your infant at least once every 2 months until your baby is about 6 months old. Not all doctors follow this routine, though, so ask about your doctor's well-baby checkup schedule.

Your infant is seen regularly to assess growth, feeding, and sleeping habits, among other things. These regular checkups also allow the doctor to follow up on any concerns from previous checkups and are a chance for you to ask questions about your baby's health or behavior.

What Happens at the Office Visit

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

Address 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.

Immunizations Your Baby Will Receive

At 1-2 months old, your baby will receive the second dose of the hepatitis B vaccine (HBV) if the first dose was given just after birth. With combination vaccines, however, the 2-month visit may be the first time your baby receives any immunizations.

At 2 months (and again at 4 months), your baby will be given several immunizations:

Babies at high risk of developing a meningococcal disease, which can lead to bacterial meningitis and other serious conditions, may receive an additional vaccine. (Otherwise, the meningococcal vaccine is routinely given at 11-12 years old.)

Some of these safeguards against serious childhood illnesses can cause reactions (usually mild), such as fever or irritability. Be sure to discuss side effects with your doctor and get guidelines for when to call the office.

When to Call the Doctor

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

Again, don't hesitate to contact the doctor's office about any health or behavior concerns.
