@emily_paige65,

if i let her my daughter can sleep 4-6 hours but she stays awake for feeding and takes 4ozs then plays for a bit and falls asleep (when she doesnt have a tummy ache)

honestly in my opinion I'd let her sleep until she wakes on her own...unless she hits like 6hrs with out eating...since she is newborn...but I think they will wake when they want for my 2nd baby I would try to wake her if she slept to long but I'd play with her and what not to keep her up to eat..but she would eat an 1oz out of 3oz and fall asleep
