My daughter sleeps all throughout the night besides when she wakes up to eat and diaper changes. She only wakes up twice. The past couple days she will be content for a while than she will start to get fussy. Keep in mind she will already be fed and have a diaper change. When she gets fussy I try to make sure she doesnt want any kind of attention but every time it turns out to be she is tired. She seems to be fighting her sleep during the day a lot. Has anyone else been through this? Any tips?
