I have to take a friend and her child to an appt this afternoon and have no idea how to instal her car seat in my car. Here is the info can someone give me some quick advice. I drive a 4runner (94) I have my sons Graco Nautilus and her Serena hers has to rear face. My big problem is no matter where I put the rear facing one once I tighten the seat belt it flips the car seat into the back of the seat. I am assuming that shouldn't happen. I have tried rolling up a towel under it to level it out but it doesn't help much. I can put it in the middle with a lap belt only (put locking clip on belt) or on the side with a lap/shoulder auto locking belt. Normally my sons is in the middle but his is easy to instal and I can put it anywhere. Please advise!!!!!
