Avynlee is pretty big baby. She has almost outgrown her infant carseat and is not quite 8 months old. So, we need to start looking into getting her a new one. She obviously still needs a 5 point harness and should probably stay rear facing. I am debating between a convertible carseat and a high back booster with a 5 point harness. The boosters I have looked into are foward facing only. If I got a convertible one, would she just use the backless booster seat when she grows out of the convertible one? I'm just wondering what others' experiences have been. Any tips?
