2-month-old dd has become quite the noisy sleeper the past week or so. She always made some noise while sleeping but it seems she is much more vocal lately, to the point where I can't distinguish if she is awake or asleep. I think I got up 4 times last night ready to feed her, only to find her sleeping in her crib. I even asked dh to get up last night too to look. She squirms a lot too, has hand in her face which ped says is her self-soothing. Is this normal? When does her sleep start to normalize?
