I've got the same age gap as you I think, about 21 months, but I walk all of the time all over the place. We ended up with a second hand P&T sport. We live rurally and everything is on the main street, so no point taking a car, but at the same time when I look at where DD is at now, asking her to walk that far down, and then around and back, will probably be too much. Especially when the weather isn't ideal and we need the covers on.
So I guess it just depends
