My DS, 2 and a bit, seems to find it impossible to sleep under any bedclothes. He either protests in the first place, or shakes them off during his nocturnal gymnastics. At the moment he wears a vest underneath cotton-knit pyjamas. If I wake I go in and put a blanket over him as it seems chilly by 5 a.m, but he still shakes it off. I'm under a 13 tog duvet, and wonder how he can be warm enough. He wore a grobag last winter, but won't tolerate one now. How many bedclothes do other toddlers sleep under?
