Quoting cmja92:" Hes already a good sleeper. Only wakes up twice a night to feed and be changed. What are everyones ... [snip!] ... on them sleeping through feedings like 4 to 5 hours? Let them sleep or wake them after so long? Ive been letting him sleep???"
I don't wake up a sleeping baby unless there's a bomb threat and even then I'd have to think about it.
Seriously though, they wake up when they're hungry. Babies are built to get as much food/sleep as they need automatically. The only time them sleeping too much is an issue is when they're preemies or if they have some type of dietary issue/dehydration from some sort of sickness going on.
