With the rumble seat? So I see that the rumbleseat always is rear facing, which I don't totally mind. If you had the other seat forward facing they're looking at each other which is probably fine. Just have to hope one won't kick the other in the face.... but my question is once the younger baby is old enough (is it 6 months?) can you put them in the rumble seat and put your toddler back on top. DS is 31 lbs now, I know they grow at a slower rate but I am worried about the 35 lbs weight limit on the rumble seat, but I do like that it is higher, even if only a couple of pounds, than the P&T....
eta: the Chicco adaptor says it is just for Keyfit, does anyone know if that means it excludes the Keyfit30?
Re: anyone have the uppababy vista?
Yes, you can move your younger baby to the Rumbleseat but remember it does not recline for a nap. The Uppa Baby also pushes a bit easier if you do move the bigger child to the top seat.
I still have my older child (34 lbs) in the Rumbleseat but I may have to move him to the top seat soon.
Off the top of my head - I'm not sure about the Chicco adapter. I would suggest calling Uppa Baby to make sure.
