my ds is waking up cold in his sleeping bag - even though we put a body suit on as well as pjs and a jumper. He is 23months. Have tried putting a blanket on but because he moves around so much it just ends up in a pile in a corner of the cot. Am wondering if i should get a light duvet (4.5tog) and keep him in the sleeping bag with less clothes. Does anyone else use duvet + sleeping bag? I know all the advise is for less clothing - but he wakes up with cold feet as well as arms and hands! Nb room thermometer reads 16.
