I saw a mom at my son's daycare who uses a really cool insulated container for her kid's meals. It looks like a bowl (or thermos) with three divided sections and apparently, if it is filled with hot food, the food stays warm until serving. It comes in its own little insulated carrying case and the whole thing is probably no bigger than half the size of a regular lunchbox. Do any moms here use such a thing? Where can I get it? I haven't seen the daycare mom in awhile or I'd ask her directly!
