They may be especially concerned if they are at the lower end of the growth charts.
Occasionally, parents of a big baby will worry that they are feeding their baby too much and wonder if they need to put their baby on a diet.
Is it possible to overfeed a baby at this age?
Sure, it is possible, but not common unless you are really going out of your way to try and overfeed your baby. This would include giving your baby extra calories, especially juice, or putting a lot of cereal in his bottles.
If you are solely breastfeeding or giving your baby an iron-fortified infant formula, then it is unlikely that you will overfeed your baby. Most babies will stop eating or will spit up once they have had enough to eat.
Amount of Formula FeedingsThe American Academy of Pediatrics, in the book Your Baby's First Year, states that "Most babies are satisfied with 3 to 4 ounces per feeding during the first month, and increase that amount by 1 ounce per month until reaching 8 ounces." Although not an absolute rule, as a general guideline, that would mean that a baby would be drinking about 4 to 5 ounces per feeding during his second month. By three months, he might be drinking about 5 to 6 ounces at a time.
If your baby is drinking much more or less than that amount of formula at this age -- about 32 to 40 ounces a day -- then you may be overfeeding him.
