Our 2-month-old can't seem to get enough formula (similac advance) at night. He feeds about every 3.5 hours during the day, taking anywhere between 5 and 7 ounces at a time (overall he takes between 35 and 40 ounces a day). When we put him to bed, however, that schedule changes...
...Last night was the worst scenario; between 1 am and 8 am, he took around 23 ounces between 4 feedings throughout the night. Holding him off and distracting him is no option, he screams like we've starved him for days.
Besides the fact that this is frustrating as we get no sleep (we are considering a nocturnal lifestyle these days

), should we be concerend that he is not getting the necessary nutrition from formula? Should we be mixing in some infant cereal?
I know every baby is different, my wife's close friend gave birth 3 weeks before and her infant (on the same formula) has never exceeded 25 ounces per day.
