My LO is nearly 8mo and weighs about 10kg / 22lbs. According to feeding guidelines he should be "on average taking in about 2½ ounces (75 mL) of infant formula a day for every pound (453g) of body weight" i.e. 1650ml, but he is only having a 120ml bottle 5-6 times a day and is often unable to finish the bottle. His daily formula intake can go from 300ml to 700ml. I breastfeed him only once a day.
He does not seem to have a problem in putting on weight, however, since we switched from breastfeeding to formula feeding about a month ago, he has dropped about a pound in weight but is still in a high percentage ( >80%) in proportion to his height.
I am keen to know how much other formula-fed babies drink?
