During the four month visit, your doctor will measure the baby's height, weight, and head circumference, and plot that on the baby's growth curve. Parents are always interested and excited to know how their baby is growing.
At four months, your baby will get the second set of vaccinations, which are usually the same set of the first vaccinations that the baby got at two months. So that will again be Polio, Diphtheria, Tetanus, Pertussis, Pneumococcal vaccine, Hepatitis B, Haemophilus Influenza Type B, and Rotavirus vaccine. Depending on the doctor's office, you need to discuss with your doctor your baby's vaccination schedule.
At four months, parents have a lot of questions about feeding issues. Some babies are exclusively breastfed, and the American Academy of Pediatrics recommends that we breastfeed babies exclusively until six months.
Some bottle-fed babies will start eating cereals at this age, and you should discuss that with your doctor. At four months of age, you can also start water for your baby, especially on excessively hot days.
Some babies will also start taking solids. Each family and each doctor has an individual style and you should discuss that with your pediatrician.
One final thing to remember is that at four months, most babies start to roll over, so you want to make sure there are no loose blankets or toys in the baby’s crib or bassinet. Never leave a baby unattended.
The next visit after the four month visit is the six month visit. Be sure to discuss with your doctor what the new milestones will be that you should look out for as a parent.
