I found out why Isaac was dropping all his blankets out of his crib. He was trying to escape! Sunday morning when Tim went in to get the boys he found Isaac crawling around on the floor. We have no idea how long he had been out of his crib and I never heard him fall. We have all hard floors, no carpet. A few months ago I got a huge bin of foam mat puzzle letters (whatever you call them) at D.I. and I put them on the ground below their crib and at the bottom of the stairs. Hopefully that cushioned the fall. On the other hand can't be one hundred percent sure I actually put him back in his crib after giving him milk at 4 am.
