We have a Britax B-Agile double. I was thinking about buying a belly bar or a tray, but then I got to thinking about it and I am not sure I see the need. I feel like it would make it hard to get them in and out. Plus, we have to lug our stroller up and down two flights of stairs every time we use it, so any extra weight is something I really consider. But we are just starting solids, so maybe I am underestimating the value of something to put a snack on? And there's not any really great place to hook toys onto, though we make it work - it just means a lot of links for the girls to be able to reach anything.

Relatedly, is there a good travel bag for the B-Agile double? Britax doesn't seem to make one and I am trying to decide if that's just because they assume you'd have to be insane to fly with one.
