What could be causing my daughter to sleep so restlessly? She is 4 months old and up until a few weeks ago, she was sleeping relatively well (10 til 5 or 6). However, she stirs a lot as she is falling asleep and also during the night. She starts stirring with her head going from side to side and if the paci is in her mouth, she rips it out, she grabs her head and ends up pulling her hat down over her eyes. I don't think it has to do with her needing to soothe herself back to sleep because it happens when she is by herself in the crib but also if I go in and try to soothe her, hold her hand, or even if I pick her up and hold her. She is trying to sleep though, because she falls alseep for a few minutes before something wakes her. Sometimes she is in and out of sleep for 20-30 min and then she falls into a peaceful sleep, other times after 30 min she wakes up fully and wants to eat....even though I'm pretty sure she's not hungry. Sometimes I wonder if she has a burp but I've tried picking her up and it doesn't help. I've tried picking her up and changing her diaper (which is usually wet) and that also just wakes her up and then she wants to eat. She is napping well, so I don't think she is overtired. What could be causing this???
