My grandson is 2-1/2 months old. His mother insists he is never full, so instead of inceasing the ounces of formual, she is down to 3 oz per feeding and putting a tablespoon of rice cereal in each feeding. Not sure how many times he feeds a day, but at 3 oz ... I am so afraid he is not getting the proper nutrition or the amount of formula he needs for his developmental growth. He is good in weight and height - not udnerweight, growing very well, etc. But this is worrisom. Are there not standards on how many required ounces of formula an infant should have per day? thank you!
