My daughter who is 11 weeks has started sleeping ALOT -very out of character for her. She was colicky up until 2 weeks ago. She eats every 3-4 hours (wakes for her feedings) but goes right back down... then she'll have an awake period from about 6-12AM. Is this normal? I'm thinking she is going through a growth spurt or maybe this was how she always was and her colick was keeping her up? Any thoughts? Did any of your babies go through this?
