Instead, look for contentment between feedings, alertness, good skin tone and steady weight
gain — about 4 to 7 ounces a week for the first month.
Know the signs of
underfeeding. If your newborn isn't gaining weight, wets fewer than six to eight diapers a day or doesn't have regular bowel movements, seems sleepy all the time, and shows little interest in feeding, he or she may not be getting enough to eat. If you notice any of these signs or have concerns, call your baby's doctor.
