My soon to be 12 week son only drinks at most 4 ounces every 2-3 hrs, usually more like 3.5. (I exclusively pump)...anyway some of the info I checked that I was given upon leaving the hospital said that from 0-2 mo they drink 2-5 ounces and from 2+ it's 4-6. He is now 12.5 pounds and according to his weight it said he should eat 30 ounces of BM per day. He is lucky if he takes 24. He was 6 11 at birth so heis gaining well, but I fear that he is not eating enough, anyone have the same issue. I think I may have written a similar post but I just need some reassurance.
