Mel, I think a lot of people actually use cot sheets!!

I stopped wrapping Elijah about 2 wks ago - cold turkey straight into a grobag. His sleeping went feral and he was trying to suck his fingers. It took a few more nights to settle his sleeping so I'm not sure what upset his sleeping overnight but we're back to semi decent - not as good as he was before he went all feral with it though lol.
