My 3 week and 5 day old will not sleep on her back longer than 10 mins! She crys like she's got reflux or something.. she will sleep in her pod .. in her tummy! I only ever allow this if I'm able to watch and ensure she is safe and breathing fine.. I also never leave her in this possition alone in a crib or at night time.. but at night time the only way I can get her to sleep is cuddled in.. and again that then means I don't sleep because I feel far to unsafe she will not be swaddled the last time I swaddled her she cried her eyes out that much she was almost sick..  she likes to be able to kick and punch which I wouldn't mind if she could actually sleep.. it's now at the stage she is shattered and sleeps most of day and not at night due to nor sleeping in her back.. I've tried not letting her sleep all day (putting her in her back, she won't sleep) but she still doesn't sleep at night on her back? IDEAS???
