For the first six months of your baby’s life, the only nutrition he needs is breast milk or formula.
The American Academy of Pediatrics recommends breastfeeding over formula. Formula is not identical to breast milk, but formulas do provide an appropriate level of nutrition. Both approaches are safe and healthy for your baby, and each has its advantages.
Newborns need to be fed every two to three hours, but a strict feeding schedule isn’t necessary.
Breastfed babies need to eat more often because breast milk digests more quickly.
Don’t be alarmed if you notice your baby has lost weight in the first week; most infants lose several ounces of weight during their first week, but they should be back up to their birth weight by the end of the second week.
If your baby sleeps for periods longer than four hours in the first two weeks, wake him for a feeding. If your baby will not stay awake long enough to eat at least eight times per day, call your doctor.
