i brought one of those grobag egg thermometer things from Toys r us the other day and am testing out the temperatures in our bedroom... i am a bit worried as i can't seem to get it to go down below 23 degrees.... I have the heating on at th emoment but its set to come on at 19 degrees... and we always have our bedroom window on the catch to air out the house..... don't know what to do to get it cooler for when our LO arrives so he/she can sleep with us in our room?? any ideas?
