My little guy is 4 1/2 months, and has been on a great 3 hour schedule since day 1. We are slowly moving him to a 4 hour schedule, as he didn't progress their on his own, and our ped thinks I should cut back on his feedings - he was born at 6 pds 14 oz (at 36 weeks), and is now 15pds 4 oz - a very big boy. Problem is that, although he is a perfect napper and has no problems during the day, he is up at 4 or 5 every morning, and not to feed. He would eat (he'll eat any time), but shows no signs of hunger being the reason for waking. We do PU/PD for 2-3 hours - until 7, when we start the day. I am exhausted. HOw can I get him to sleep longer??? (BTW - other than this morning waker, he is an angel baby - although he did have a 2 month grumpy stretch)
