My baby sleeps so much!

Abbie
Is it normal? She is 9 days old and she sleeps sooooo much especially during the day. For example I fed her Today at around 1pm and she is asleep by 1:15, I then had to wake her at 4:30 to feed her again and she falls straight back to sleep, I woke her at 6:30 to feed her and now she is awake! But is it normal for newborns to sleep that much!
