I'm so upset...can someone please advise me?

Sadly this is a completely normal reaction for a good first time mommy. In my opinion fear keeps us on our toes lol My daughter slept better on her tummy too and it scared me so for the first 8 months or so she slept on her tummy onmy chest...this allowed my paranoid butt to sleep and her to sleep the way she wanted. Cribs terrified me for whatever reason and she went straight from sleeping inour bed to sleeping in a toddler bed. She is now 26 months old and a fantastic sleeper :) It gets less scary when you know they can roll over if they cant breathe or take the pillow off thier face. Hang in there!
