Hi All, I have 17 month old twins (one of which has only just started walking and the other still can't walk!) and I am 7 months pregnant (with 1 baby, thankfully) - Just wondering how do-able it will be to push a double pushchair with baby in a sling? We're hoping that we'll be able to do this until we can get one of our twins on a buggy board as we really can't afford the expense of a triple pushchair. For big trips out we've got a double & a single so if me and OH are out won't be an issue.
