anitha dont worry as long as he is drinking milk let him drink how often he wants. change of atmosphere from hospital to home probably is an exhausting change for him and he gets tired from sucking so instead he will feed lesser amts more often. So if he is supposed to drink 50 mls every 3 hrs that means he is supposed to drink 400 mls per day. so is he drinks 30 mls every 1.5 hrs he will actually take in 480 mls ... which is great! just make sure and burp him after every feed and hold him upright for some time. if you have extra milk from pumping just freeze the extra for usage later or donation. premie milk is a premium that you can share if you want through milkshare, a yahoo group.
