A. That amount of formula is below the 24 to 32 ounces of baby formula that you would expect a 5 month old baby to eat.
Among the reasons why an infant might be drinking less baby formula like this include that:
- he is going through a little slowdown in his growth, although this should only last a few days or so
- you are feeding him too many solid foods, and much more than the 3-5 tablespoons of cereal a day and 1-2 tablespoons of fruits and vegetables once or twice a day that a 4-6 month old baby might be eating. Keep in mind that some infants aren't even eating cereal until they are 6 months old, so any amount of fruits and vegetables could be too much for some babies.
- the nipples of his bottles aren't letting enough formula out and he is getting frustrated. If this might be the case, you could consider upgrading to a medium or fast flow nipple for his bottles.
- you are either waiting too long to feed him or are feeding him too early. Either could cause problems and you might experiment with the timing of his feedings to see if it makes a difference.
- that he is teething, although you should feel or see some teeth if this were the case.
Or it could just be normal. The fact that 24-32 ounces if the average intake of baby formula means that some are drinking more and others are drinking less, and all can be healthy and growing well.
