OK, here is the pic. This was just extra material I had laying around... these two are available, if you are interested. The one I made Turbo was from scrap material that wasnt too cute nor picture friendly! haha.
I tested it out. In the microwave for 3 minutes, and sitting on our dining room table (with a window that my daughter had cracked open...unknown to me) they stayed warm a little over 2.5 hours. Now, if you put this in your babies blanket and with him/her laying on top of it, I am positive it stays warm a few hours longer, I know when Turbo and Callie wake up, they don't want to get out of bed!
