Is My Baby Eating Enough?
In the first few weeks, it's hard to tell if your baby is getting enough milk, so see your pediatrician often to track weight gain.
In the first month, a well-nourished, breastfed baby will have six to eight wet diapers per day and three or four with stool. If you feel your baby sucking vigorously, hear him swallowing, feel your milk letting down (this is sometimes accompanied by tingling) and see your baby drifting contentedly off to sleep, chances are he is well nourished. While it's normal for babies to lose a little weight after birth, weight gain is generally the best indicator he is eating enough. Well-fed infants usually put on an average of 4 to 5 ounces a week for the first few weeks and an average of 1 to 2 pounds per month for the first six months.
It's easier to tell if a bottle-fed baby (breastmilk or formula) is well-nourished. Many newborns may only take 1 to 2 ounces at each feeding for the first week. By 1 month of age, most infants are up to 3 to 4 ounces at each feeding. Ultimately, it depends on baby's weight, body type and age, but as a general guideline, a bottle-fed infant will usually consume an average of 2 to 2 ½ ounces of breastmilk or formula per pound per day. So, if your baby weighs 10 pounds, she may take 20 to 25 ounces per day.
