4 1/2 yo has outgrown Britax Marathon - What now?

[mamatoablessing]

She's 47lbs and about 46 inches tall.  She's done with the Marathon but I don't think she's mature enough for a HBB yet (she's used her sister's a few times and won't sit still and straight).  I looked at the Nautilus but wow, it's almost $200. We need two seats btw; one for my car and one for DH's.  Any other options for a seat that can turn into a HBB when she's ready?

Thanks so much!

Are you in Canada?  If so, the only real options are the Nautilus and Frontier (which is more expensive).

In the US there is the Evenflo Maestro (but it only harnesses to 50 lbs so it wouldn't be useful for you).  There is also the Evenflo Generations 65, which she might fit in if she has a short torso.  If she's even with the top straps on the Marathon, she would be maxing out the Generations as well.
