DS 2.8 goes to bed under a 4.5 tog duvet wearing a short sleeved pyjama top and nappy - that's all
However since the weather has become more summery, he's really sweaty and red whenever I check him. This has gone on for a week or so, so it's not illness related. Our house is pretty well insulated and his room is next to the airing cupboard so it is about 21 degrees in there at the moment (with the window open!)
In previous years I'd have put him in his 0.5 tog grobag but now he's in a big boys bed I'm stumped! I don't want to put just a sheet on him as I'd worry that might be too cold, and he always seems to get twisted up in blankets
I've looked online and I've found a 2.5 tog duvet but it's £32.99 which seems a bit steep. I just wonder if I'm missing something... I suppose it could be the waterproof bottom sheet making him sweaty but I don't really want to take that off
What do you lot do?
