Just that really-we have a narrow front door and our Out n About was useless with dc1 and dc2, baby jogger city mini twin also won't fit. I'm now expecting dc3 and really want a side by side as my toddler just won't be happy in anything else. But he's really big. We've tried out the Mountain Buggy duet in John Lewis but you don't get much of an idea on the shop floor.
Dh thinks it's perfect because it's so narrow but I'm worried how long it'll last and how comfortable dc2 will be-he's already 20 months and off the graph on the centile chart. I'll be doing the daily school run with it so need a reliable buggy! (it won't need to fit in the car).
Any thoughts? Thanks!
