Today I ordered the babe a big girl car seat. After hemming and hawing between the Britax Roundabout, Marathon (which A has) and Boulevard, I ended up going with the Boulevard. It was about $30 more than the cheapest price I could find on the Roundabout, but it will last her until she's 65 lbs and it has side impact safety stuff and an infant cuddler thingie. Techincal terms and all that. So, this is what she'll be riding in....hopefully until she can just hop in the car and sit in the adult seat.
