How much infant formula will my baby eat?

Newborns should eat between 2 and 3 ounces at every feeding and they will want to be fed about every 2 to 3 hours. This will gradually increase to 4 ounces at about one month old and continue to increase as they age. Some babies will eat more and some less. As long as your baby continues to gain weight you should not be too concerned. DO consult your doctor if you note a change in your babies eating habits or if they do not gain weight.
You should also consult your doctor if you notice what may be an allergic reaction to your baby's formula. Symptoms would include diarrhea, vomiting or rash. You may also notice your baby being more fussy than normal.
Signs of lactose intolerance could also be diarrhea, vomiting and gas. Your doctor can test to confirm if there is an issue with cow milk based formula.
At around one year of age you can start weaning your baby from infant formula and feed them whole cow's milk. You should not feed your baby reduced fat or fat free milk as the fat is very important to their growth at this young age. When moving your baby to regular cows milk again be observant of their reaction and notify your doctor of any concerns.
