Anyone have a window A/C unit in their LO's room? My son's (13 months) room is super small, but also one of the hottest in the whole house. Its gets all the afternoon sun and by sunset is often hotter in there then it is outside. We're getting a rash of 80 degree weather here. Maybe even 90 this weekend.

So I'm considering this:

but worried it might be too loud, or get too cold?
