My dd 4 1/2 months loves being in her tummy. She will pretty much be on it any time she lays down during the day. At night she falls asleep on her back and will roll to her side which is fine, I just leave her but the last few nights she's been rolling into her front and then crying because she can't roll back. I've been trying to encourage her to roll back during the day hoping this will help but she's got me up every half hour where I'm having to move her back and I'm just exhausted! So is she - she's not the greatest sleeper anyway and barely ever naps during the day for longer than 20-30 mins. I'm not sure why I can do to stop her rolling? Not sure about putting blankets there as she gets hot very easily.
