When did you move to a convertible carseat? I'm trying to weigh out my options. DS is about 16bs/23.5inches. I've got the KeyFit 22. I was thinking I'd switch to a convertible when he gets a little more head control but I'm now seeing that the new Britax models are coming out at the very end of August.
Think it would be better to wait on purchasing in order to get the newer model?
