Pure Wool & Cotton 3 Tog Toddler Duvet

My two year old has been sleeping with her new wool duvet for about a week now and it's a big hit! She already slept quite well but she wakes less now during the night and is sleeping in for an hour longer too each morning. Its thin but dense as you would expect from wool. She seems nice and snug under it. Its February now so we will see how she finds it in the summer but I am very happy. I'd read reviews on other wool quilts saying that they smelt of sheep but there was no smell at all when I unwrapped it. Its lovely. We are seriously considering getting one for our bed too.

Online the sizing of the duvet isn't given, nor is it on the packaging. I assumed it would be the UK standard size (120x150cm) so bought it anyway. Unfortunately it was about 20cm short, which meant it didn't fit the duvet covers I'd already bought. The quality looked fine, though I wasn't really interested as I knew it wasn't going to be suitable. M&S, please give the sizes!
