Hello, my daughter is almost 9 months old now, thank god she is doing fine in all activities,,, but I have noticed 2 strange things which she does quite often,, 1. she sometimes moves her head left right, right left without reasons, like saying No to something with moving head.. Is this normal?? 2. secondly, she turns her body here n there, takes turns while sleeping, moves from one corner to other corner of bed while sleeping, even sometimes all of sudden starts crying for few moments while sleeping and then gets normal.. also likes to suck bed sheets, pillows while sleeping,. I want to understand, are these things normal, or anything to take care.. being first time parents, we r bit concerned..
