What age do kids remember they need to take a layer of clothing on/off when they are hot/cold? My 4.5 year old will never take his jumper off unless I tell him (he’s clearly warm and overheating with rosy cheeks). Same with being cold, he’ll play outside in the freezing cold with hands like ice - but won’t realise he needs a jacket unless I offer one!. He’s at school in six months so I was hoping he might figure it out before then as I doubt the school teachers will be as good as the daycare teachers at monitoring appropriate clothing.
