We're trying to decide on a stroller, and one of the main factors causing us to lean toward our current first choice (the uppababy vista) is that you can add the rumble seat to use with an older child.

However, if all goes according to plan, we'll have baby #2 when baby #1 is between 2.5 and 3. At that age, will the older child be using the rumble seat (which apparently supports up to 35 lbs I think)? Would a buggy board be sufficient or do they need a place to sit down? We will be doing a lot of walking and not very much time in the car, and I plan for this stroller to be our main one (So I don't want to buy a true side by side double). Thanks!
