Feeding Your Infant: Ages 0 to 4 Months

IMAGE Congratulations! You’re the proud (and nervous) parent of the world’s most beautiful baby! Giving your baby love and nurturing comes so naturally to you. So does showing him off to your family, friends, and even perfect strangers! But when it comes to feeding, you may feel a little unsure of what to do. Here are some guidelines.

What Foods Are Best?

Breast milk is the only food recommended for the first six months of life. If you cannot breastfeed or express milk, your infant should be fed iron-fortified formula. A bottle-fed baby should drink every 2-3 hours at first.

How Much Breast Milk or Formula Should I Give?

A newborn baby that is breastfed may feed every two hours even overnight. As your baby grows feed whenever the baby shows signs of hunger.
In the first few weeks, infants should be awoken to feed if four hours have passed since the beginning of the last feeding. Your baby will eventually develop a more regular feeding schedule, which may occur about eight times a day. Your infant may need more breastmilk during certain times like a growth spurt. Follow your baby's hunger signals to know when to provide breastmilk.
Newborns that are formula fed may drink 1-½ to 3 ounces every 2-3 hours. The amount per feeding will increase as your baby grows. For example, by two months, your baby may drink 4-5 ounces every 3-4 hours.

Growth Spurts

Growth spurts will make your baby hungrier. Increase breastmilk or formula as indicated by your baby's needs. Growth spurts may occur around the ages of:
  • 7-14 days
  • 3-6 weeks
  • 4 months

Important Tips

Do Not Give Solid Foods Until Your Baby Is Ready
According to the American Academy of Pediatrics, breastmilk and formula are adequate nutrition alone in the first six months. Water and juice are unnecessary during this time.
Solid food is not recommended until your baby demonstrates that he/she is ready for solid foods, often around 6 months of age. Your baby may be ready for solid foods if you baby:
  • Holds neck steady
  • Can sit
  • Opens mouth when food is offered
  • Keeps food in mouth and swallows it instead of pushing out with their tongue
  • Reaches for food, showing he/she wants some
  • Has doubled birth weight (weighs at least 13 pounds)
Do Not Give Cow’s Milk, Honey, Syrup, Kool-Aid, or Soda to Your Baby
Breast milk or iron-fortified formula is best.

What Are My Choices?

Benefits of Breastfeeding Benefits of Iron-Fortified Formula
  • It is easy to digest.
  • It contains disease-fighting compounds.
  • It is less likely to cause allergies.
  • It helps mother and baby develop a special closeness.
  • It helps baby’s jaw develop.

  • It has been found to help reduce infant obesity, respiratory infections, such as pneumonia, and diarrhea.
  • It provides adequate nutrition and is a suitable substitute when breast milk is not available.

Why not cow’s milk? Why not low-iron formula?
  • It has too much protein.
  • It is hard for baby to digest.
  • It has too many minerals and can be hard on baby’s kidneys.
  • It is low in vitamin C, vitamin E, iron, and copper, which are important for your baby’s growth.
  • It does not contain enough iron to prevent anemia.
  • It is not a treatment for constipation.

What Can I Expect?

Breastfeeding Iron-fortified formula
  • Breastfeeding is a supply and demand way to feed. The more often the baby nurses, the more milk your breasts will produce.
  • A newborn breast-fed baby will nurse an average of 8-12 times in 24 hours.
  • Your baby may need a vitamin D supplement starting in the first few days after birth. Premature babies may need an iron supplement.
  • A breast-fed baby will nurse an average of 20-30 minutes. The length of time will decrease as the baby gets older.
  • During growth spurts, your baby may need to breastfeed more often. This does not mean your milk supply has decreased.
  • A breast-fed baby should have 6-8 wet diapers in 24 hours.
  • A breast-fed baby may have a bowel movement once per day or once with each feeding. Each baby will have their own schedule. During times of growth, your baby may go several days to a week without having a bowel movement. This is not constipation if the stool is soft.
  • Breast milk should not be heated in the microwave, because it destroys nutrients and can cause hot spots that may burn your baby.
  • Everything must be kept clean. Wash the top of the formula container before opening. Wash bottles and nipples in hot, sudsy water. Rinse well with hot water.
  • Mix formula carefully, following the directions on the label.
  • Use one can of formula before opening another. An opened can of ready-made liquid formula is safe for up to 48 hours when tightly covered and refrigerated.
  • Formula prepared for feeding should be refrigerated and used within 24 hours.
  • Formula should not be heated in the microwave because it can cause hot spots that may burn your baby.
  • Formula should not be frozen.
  • If not able to keep formula cold, use powdered formula and mix when needed.
  • Your baby should have 6-8 wet diapers in 24 hours.
  • Formula-fed babies will develop their own pattern of soiled diapers. Watch for your baby’s pattern.
  • During growth spurts, your baby may need to eat more often.
  • If your baby is not eating enough vitamin D fortified formula, he may need a supplement.
