My 3 week old ds sleeps a lot better when swaddled, but I'm paranoid about him overheating. He has a short sleeved vest on & sleep suit and is then swaddled in a muslin like this www.piccalilly.co.uk/products/muslin-swaddle-elephant-blue
I then place a cellular blanket over the top (folded so equiviant to 2 layers). Is this too much?? Our room temp is 17.6 degrees according to the avent thermometer.
