I have a 2004 Cavalier Coupe. We are hoping to get a new vehicle in February with our tax money, but if we can't...wondering if its possible to have 2 car seats in there and a booster in the middle? I have a 2 year old in a Evenflo Triumph and a 9 year old in a backless booster and a new baby due in March, who will take the Graco Safeseat. I don't feel safe having my 9 year old be without a booster. She is 4ft 6 inches and 63 pounds. She looks tiny to me. I was going to have her in the middle, but I don't know if she will fit with her booster?
