DS has got a sore exczema patch on his shoulder (got antibiotic cream for this) and we think that the extra material from a sleeping bag, plus vest and sleep suit at the moment are aggravating him. He was up twice last night (usually sleeps through) and was really writhing around and trying to scratch his shoulder with his head 
Thing is I think if I use blankets rather than sleeping bag he will sleep with no covers on him as he is very wriggly. We are in a rural area and this morning it's 16 degrees in his room so I worry about him being cold.
We adopted him in the height of summer so a bit unsure about the nighttime temperature sleeping thing. Does anyone use something different that works?
