E currently have a double pushchair due to having a 19 month old and a 6 month old, but I'd love to ditch it and just get a single asap! DD is now very insistent on being allowed to walk rather than being in the pushchair, but obviously still can't walk great distances so the double is sticking around for a while yet. But got me wondering how old were your DC when you were able to wave bye bye to the pushchair completely?
