Thanks for all the replies, still not sure what to do LOL.

We lived in remote WA with DS 1 when he was born & it was very hot but we had ducted cooling that never got switched off (we didn't pay the bills lol) & he was a screamer from day 1 anyway!

This time round I'm totally confused, his room gets most the sun so when I went to put him in bed last night it was still around 30 in his room & dropped to 26 over night. We have an aircond going a couple rooms away with all the ceiling fans going. But as I'm bf I'm so darn hot anyway I can't tell if it's comfy or not. grrrrrr. I'm soooo confused as to what to even put him in to sleep. I don't want him getting his arms out & getting cold, but I don't want him too hot....far out this parenting stuff is hard, even the second time around!
