Really hot here tonight but I never know how best to dress baby for bed in this sort of weather. She's in a long sleeve babygrow and nappy at the moment with no vest underneath. The window in our room will be open overnight and she has a light aerated blanket over her. She's 8 weeks old. I don't want her to overheat but at the same time with the window open I'm worried it could turn cooler in the middle of the night.
