At 4 months of age your baby should still be taking breast milk or infant formula. At this age most babies take about 6 to 7 ounces every 4 to 5 hours. You can start giving your baby juice at the age of 4 to 6 months, but limit it to a few ounces each day.
If you are breast-feeding your baby, it’s a good idea to sometimes feed your baby with pumped breast milk in a bottle. This helps your baby learn another way to drink milk and allows other people to feed your baby.
Your baby is ready for cereal when she is able to hold her head up well, likes having food in her mouth, and can swallow it easily. Use a spoon to give your baby cereal, not a bottle or an infant feeder. Sitting up while eating helps your baby learn good eating habits. When you start cereal, start with a thin mix of rice cereal and breast milk or formula. You can thicken it after a few days as your baby gets used to eating cereal.
You can also start pureed fruits, vegetables, and meats between 4 and 6 months. Wait at least 2 days before you start each new food or juice so you have time to make sure your baby is not allergic to the new food. Diarrhea, rash, or vomiting are signs of a possible food allergy.
Don't give your baby a bottle just to quiet her when it’s unlikely that she is hungry and don’t put your baby to bed with a bottle. Babies who spend too much time with a bottle in their mouth use the bottle as a security object. This makes it harder for them to give up the bottle and start eating solid food. Babies who spend too much time with a bottle in their mouth are also more likely to have ear infections and tooth decay problems. Find another security object like a stuffed animal or a blanket.
Your baby is starting to roll over from her stomach to her back. Babies at this age enjoy toys that make noise when shaken.
It’s normal for babies to cry. To calm your baby, talk to her with a gentle, soothing voice, hold her, or try rocking, dancing, or humming. Sometimes a ride in the car can be soothing for your baby.
Many babies sleep through the night by 4 months of age and will also nap 4 to 6 hours during the day. If your baby's sleeping patterns are different from this, you may want to ask your healthcare provider for ideas about ways to keep your baby more alert and awake during the day and asleep at night.
Reading and TV
As your baby gets older, read to her every day. Choose cloth or board books with bright colors and large simple pictures.
Don't try to keep your baby entertained with TV or videos on a tablet or computer. The American Academy of Pediatrics recommends not allowing children under 2 years old to watch TV at all. Watching TV keeps children from playing and interacting with people. Babies need to be active because it helps their brains and bodies to develop.
Your baby may start teething and may drool and chew a lot. It may help to massage your baby's swollen gums with your finger. A teething ring may be useful. As your baby’s teeth start coming in, you can clean them by wiping them with a damp washcloth.
Never let your child go to sleep with a bottle. Babies can get tooth decay from having the sugar from milk or juice sit in their mouths for long periods of time.
If you find yourself getting annoyed or angry with your baby, or if your baby is crying too much and you cannot cope with it, call a friend or relative for help. NEVER shake a baby.
Choking and Suffocation
Fires and Burns
Immunizations protect your child against several serious, life-threatening diseases. At the 4-month visit, your baby should have:
Some babies also get another hepatitis B (hep B) shot at this age.
Some vaccines can be combined to reduce the total number of shots for your baby.
Your baby may have a fever and be irritable for a few days after getting shots. Your baby may also have some soreness, redness, and swelling where the shots were given. Ask your healthcare provider what symptoms or problems you should watch for and what to do if your child has them.
Bring your child's shot record to all visits with your child’s healthcare provider.
Your baby's next routine visit should be at the age of 6 months.
