My 2.5 year old is in a sleeper, under his blankie, and a comforter. He gets really hot in his sleep as well. If it wasn't for my husband, the heater in our room wouldn't even come on tonight, I get very hot too. So, with it being around 40 outside tonight, would you turn your kids heater on? I'm hot right now, but I don't want my toddler getting cold.
