I agree..if there's no weight issues and plenty of wet and poopy diapers then let baby sleep. Even at 1 day old Maddie was having at least one or two 4 hour stretches without eating. I'm also from the school of thought that you don't wake a sleeping baby (unless there's a medical reason).
Keep asking the questions Brooke, chances are many other mama's are thinking the same thing and hoping somebody posts it.
