Problem at the moment is I'm 7 months pregnant & if we go anywhere & son decides he's not walking any further I can't carry (or drag!) him home. But if I take the buggy he just wants to sit in it & not walk at all. We're hoping to avoid getting a double buggy when number 2 comes along but at the moment I can't see how it's going to work. Any tips? Son is 29 months old.
