Nina, we have a double jogger by in step as well as the sit and stroll tandem. I love the sit and stroll for trips to the mall, it is easy to maneuver but the back is not that comfortable. It worked great for me since Alexis was almost 3 when Ashley came, but you probably need a regular double. The graco duoglider was recommended to me . If Finn naps at all in the stroller don't get the sit and stroll since it is almost impossible for the older child to sleep in it. That said, I love mine but Ashley is in the front of it, not the back.
