oh totally normal! I didn't feed Alasdair enough (I didn't do it on purpose) when he was first born and he was awake a lot (not necessarily crying) then suddenly when he started getting enough he'd feed, sleep, feed, sleep. It was amazing! It'll probably change quite soon but when she's having growth spurts she'll still sleep a lot. Alasdair has days/weeks where all he does is feed and sleep still!
