During the day Sadie usually wants to eat every 2-3 hours, and will wake herself if she's asleep. But, at night she will sleep longer than that if we let her. We've been waking her at the 3-3.5 hour mark to feed, since she lost a lot of weight after birth. At 2 weeks, she's above her birth weight, so I'm wondering if we can stop waking her to feed at night. When did you start letting your LO sleep as long as he/she wanted?
