Hadn't thought of flannelette sheets. But how do to do a heat pack/hot water bottle - just let them grizzle a bit longer when you get up? That's my problem... Takes so long to warm up a heat pack or hot water bottle... I guess a bit longer won't hurt him...

I was thinking of some sort of heat pad that I could turn on when I get him up... But would that be considered dangerous, like a possible cause of overheating??

Off to Target today I think to check out sheets.
