My Australian auntie has very kindly sen my dd (14 wks) a baby sheepskin, it's wonderfully thick and would almost fill her cot. I have a little sheepskin already that goes in her pram carrycot, but I'm wondering what to do with the new super douper one. As its so cold at the moment I thought I might put in her cot for her to sleep on at night, but before I do is this ok to do? She sleeps in a grobag with a vest and babygro and I don't want to overheat her. I know sheepskins are supposed to keep them warm in winter cool in summer but are they ok to use for night sleeping?
