Dd would take a bottle at 10pm and 5am starting at 2 weeks. She did this on her own, as I don't wake a healthy happy sleeping baby. Ds was every 2-3 hours till 8ish weeks, at that point he would go from 8pm-8am. He also did this on his own. I've heard it's more about sleep cycles and self soothe ability than real hunger? Not sure if that's true or not?
Sorry if I haven't gotten back with anyone via PM. Still learning the iPhone app and not very "techy".
