This might be a dumb question, but we have a Mountain Buggy Duet and they only make a car seat adapter for the Graco Snugride. We need this adapter so we can snap our infant seat on the double stroller. I was wondering, and I know this is a long shot, if anyone knows if there is any other car seat that would work with this adapter? I'm not a big fan of the Snugride and I wish we had more options!
