DD was 2 when had DS we didn't get a double but the found one in hard rubbish when DS was 6 weeks old and it has been useful and still is (almost 4)for getting them to childcare and to train station plus a couple of local parks that are too far to walk. It doesn't go in our car so don't use it anywhere go in car (and that hasn't been a problem), and never needed it in shops. So whether you need one depends on child really and how much they like walking and how many places you go to on foot where need to be on hurry (eg train station and childcare for us). We had a board for our Vouge but DD always preferred to walk but saying that the boards on the Bugs work better I think. I would wait and see how your DD is closer to having baby and then make decision.
