This is for people in the UK which, at least as far as London goes, is very hot tonight. My dd's 20 months now so we went through the very hot summer with her last year but she was much younger and didn't notice the heat so much so we just put her to bed in a nappy and used a fan. We live by a railway line and a park so it's way too noisy to leave her windows open. This year she's too old to just go in nappy as she'll take it off and she's decided she doesn't like the noise or presence of the fan. Tonight I've put her to bed in just nappy and 0.5 tog sleeping bag, do you think that will be cool enough? Her room was pretty warm this evening, this is a warm flat in general, lots of big windows.
