What about a sleepsuit that is a pullover instead of a zip-up? Sweatpants and sweatshirt? Zip-up pajamas put on backward so the zip is in the back? My dd started to undo her sleeper in the mornings as winter ended, I just got her a sweatshirt and sweatpants with some socks....my dd will NOT keep a blanket on!!! Now it's warmer here...so not as big a deal.
