My sister is due in November and I have been trying to find her an infant seat. The problem is, she drives a Saturn SL2 which is a small car and she has a daughter who will be 6 at the time. I don't believe she can get the baby in the center and my niece outboard so both seats will need to go outboard. I need to find her a seat that will fit in a very small car behind an outboard seat. So, does anyone know what the smallest seat is from front to back for me to try?
