Someone's reply to my other thread got me thinking. My ODD will be 3 next month. She is 85th percentile for height and weight and she has a long torso. She currently FF's in our car. I'm looking at getting a second seat for her and I'm wondering if I should be looking at convertibles or should I be considering something like a Frontier for her? It never even occurred to me that I might consider a seat like that for her now. Safety followed by comfort are my top priorities. What would you do? I would like to stop having to buy seats for her. We had a diplomat, recaro signo, and a true fit currently in my car.What do you think?
