Toddlers room is 27 degrees +

Just a nappy or sleeve less vest . We also have a black out blind which does wonders for keeping the heat out .. also keep the fan on in there constant if you need to buy another then do so there's second hand ones. And also put a bowl of ice in front of the fan and this also helps

Also a dogs cooling mat does exactly the same things as the ones designed for humans and there cheaper !

My daughters room in currently 30° and I’m freaking tf out ! We have a fan on and it’s doing nothing and she is so sweaty it’s genuinely terrifying

get a dog cool matt and put it under the sheet of her mattress xx ice infront of fan and a black out curtain or blind . I believe you can get a pop up black out blind its grow time or somthing but put it up at night when its the coolest not in the day as it can trap heat also

Chill max air conditioners are pretty good as you can freeze the filter too

Hang a wet towel on a chair in front of a fan !! cools the room down massively . Our bedroom is a loft conversion so we also hit those number 🥲 hope it helps for the incoming heatwave 2.0
