Girls, my little one is 5 months and 3 weeks old, always give her a bottle at night (we're on IV), she used to fall asleep well, but now she falls asleep, but then wakes up trying to roll over, and when she rolls over, she gets excited and wakes up, I have to hold her hand all night so she doesn't roll over (the whole body is getting stiff) and not wake up, how to fight this? I want to sleep normally.
