DD wiggles a LOT at first when she gets put down to sleep, especially at nap time. I'll put her down in the dead center of her mattress, she'll end up smushed at the foot of her crib against the side. Last night I came in and she was sideways with her feet up on the side. I had asked on here yesterday about her getting her feet stuck in the slats, and I think we're going to give the sleepsacks a go. So, what are suggestions for a baby who's pretty mobile in her crib AND runs hot? I think the Halo ones would be too hot for her. We have a Skip Hop one with ventilated sides that's nice and lightweight. Any other recommendations? Are the A&A ones decent? Thanks!
