Temperature currently only drops to about 19c but will likely go lower in the coming weeks. He's in long sleeve pyjamas or a footless romper with a 2.5 tog sleeping bag. He doesn't feel cold to touch but the room feels cool to me and I like to be toasty! He wakes super early but I'm not sure if that's the temperature or not.
When would you add another layer, eg vest? Do yours wear socks?
