DS is almost 6 weeks old. He recently started sleeping longer stretches at night. I recently started giving him 4 oz in a bottle. If he sleeps a longer stretch at night, I can only get 7 bottles in per day. I don't think the 2.5 x weight applies to him well as he is somewhat behind the growth curve due to emergency surgery at 13 days.
Do I continue to let him sleep his longer stretch at night and then continue to wake/feed at 3 hour interverals the rest of the time. Any other suggestions?
