It's been really hot here and it's not going to cool off anytime soon. I have DD rear facing in her carseat in the middle seat. There are no AC vents in the backseat. I blast the AC and try to angle the vents to get her air but every time I go to get her out she's hot and sweaty. If I FF her then she would be fine but I'm trying to avoid that. Any suggestions on how to keep her cool?
