DS (ASD) loves playing in the snow, but has no sense of temperature and tends to sit a lie in it a lot so he ends up frozen really quickly. 
Looking for suggestions for keeping him warm. I'd love some kind of all in one snow suit so there's no uncovered gaps, but he is a l08 cm so seems to be too big for a lot of the fleecy suits I look at, (we have largest regatta fluffy puddle all-in-one which is lovely but way too short in the leg)
Any ideas?
