Toddler sleeping in warm room..

So my almost two year olds room is so warm… 79 degrees.. we went to buy a new AC over the weekend because we moved and don’t have ones that fit our new windows, but of course they had literally nothing so we had to order online and everything is back ordered because of COVID. I have him in light shorts and a t shirt, his ceiling fan is on high and his windows are open. I don’t know what else to do, I worry about him sleeping in the heat. My husband keeps saying they did it back in the old days he will be fine. This is when my anxiety gets the best of me…
