If M's seat is in the middle, she doesn't get any air (in the pilot, the rear seat vents are in the middle console so it just blows right on the car seat base.)
Did you move your child to the side so that they could get better a/c when the summer came around?
The only other thing I could think of to help with the heat would be to buy a clip on fan with foam blades and attach that to the headrest so it could blow on her (but I know that could be dangerous if we were in a wreck)
