LO rolling onto side against crib rails, giving herself a stiff neck.

Toni

So my Lo just turned 10 months. I put her down on her back in the middle of her crib. She keeps rolling around all over in her crib, on her side or on to her stomach up into the corner. I have tried sleep sacks and it doesn't help. It freaks me out, i know she is to old for SIDS but it's scary. She also keeps giving her self a stiff neck. Can't turn it well one way. Do you guys do anything to keep your lo in place at night?
