Sleeping too much?

Rachel

My daughter is 5 weeks today. She started sleeping more during the day about 3 days ago. Her normal awake times used to be in the morning, now she sleeps for pretty much the whole day. She eats enough because I wake her to feed but then she goes right to sleep.

Before she started these long bouts of sleep she was eating alot more than she normally did.

Could she going through a growth spurt or should I be worried something is wrong?
