I have an 8mth old and he has been waking at night and screaming while he cries when I put him back to bed (normally after a feed and a cuddle). Putting aside that he's fed and cuddled... We may have figured out he's cold in his cot.

I have a sheepskin and an acrylic "wool" underlay thing. Is it safe to put his sheepskin under his flannelette fitted sheet to keep him warm? I think the SIDS guidelines say don't put baby to sleep on a sheepskin (or something), but I also don't think the acrylic thing will be warm enough.

What should I do?
