We have a heater on in Jacob's room. When we were in the Mother & Baby Unit a couple of months ago, they had his room heated too, so obviously hospitals do it too!!

Jacob wears a singlet, a short-sleeved body suit and either a wondersuit or flannelette pj's to bed, and sleeps in a sleeping bag. And then his room is heated on top of that. Initially I thought this was way too much, but not according to the hospital when I asked them.......
