My little boys room is 23 with a fan (just bought an air con unit from Amazon coming tomorrow to hopefully bring it down) he’s in a 1 tog and footless sleepsuit
Room is 20.5 and shes asleep in a 1.5, sleeveless vest and footless onesie. For tomorrow I’ll probably just do a long sleeve vest on its own (no bottoms) and the 1.5
My little boy is currently in a 0.5 because he’s always so warm! Asda do a lovely 1.5 tog. However I got my sleeping bag on Amazon prime for £5, I’ve used them since he was little and they are so good! x
