DS2 is 8months and has cough/cold. This evening it has turned asthmatic, he's had inhaler etc and the wheeze has lessened but everytime we lie him down he coughs himself awake again. His cot is already propped up on books (can't prop it any higher as he would slide down to the bottom). If i put him in his buggy he seems to sleep better as he can be more upright - but would it be ok to let him sleep in the buggy all night??
