We will be having baby #3 in May and I am starting to look at car seats and strollers. I am pretty sure I have the car seats narrowed down to the Chicco Keyfit 30 and the Britax B-Safe 35 Elite. As far as strollers go, I really like the Baby Jogger City Mini and the Britax B-Agile. Here is my issue. I very slightly prefer the B-Safe over the Keyfit and I very slightly prefer the City Mini over the B-Agile. I have heard, though, that the adaptors for Britax that I can get for the City Mini can leave the car seat pretty wobbly. So, this might override my slight preference for this combination, but I am not sure. Which combo would you choose?
