How long do I have to keep waking DS up at night to eat?

I never had issues with DD. She would get up nearly every 2 hours for the first 5-6 weeks. With DS it is completely different. He is a sleeper and waking him up even every 3 hours is a struggle. I have been setting an alarm to get up every 3 hours to feed him. However last night I must have been tired and turned off the alarm and went back to sleep. DS slept for 5 hours straight before I woke up and realized I missed his feeding. Not really sure how much longer he would have slept, but by then it was pretty easy to wake him up and he ate really well.

My concern is that he is under (not by much) his birth weight. He was 10 pounds at birth but was 9 pounds 8 ounces at his 2 day discharge weight check on Sunday, which was up from the 9 pounds 6 ounces he left at. I also worry about my supply and keeping up with his needs as he gets older if he is not eating well now.

Anyone have suggestions or advice? What should I do?
