This is probably a stupid question but if my dc (9 weeks) is sleeping through it what is the danger in a room being too warm? It's 23 degrees and she's in her usual sleepsuit and vest (strappy) and in a 2.5 tog bag with one of the inside panels removed. Don't want to wake her to remove clothes as worried she won't go down again (although I will if I have to). I've opened the window but not a breath of wind outside so it's not really making a difference.
