Maxi cosi adaptor for Britax help!

Erica • Have a beautiful 9 year old daughter and now pregnant with my second little pumpkin! It's a boy!!!!
We are getting the Britax affinity stroller but not the car seat that goes with. We're wondering if The Britax adaptor works for the maxi cosi ap infant car seat or should we just buy the maxi taxi stroller to go along with the car seat?
