For the in laws when they have twins for 1-2 days a week.
They catch the bus when it's dry but it needs to fit in their vauxhall insignia boot as well (which is big I think).
Babies will be 9 months when they go there.
Would like to buy second hand but would be prepared to spend for the most compact/appropriate buggy.
I'm a side by side type person so haven't looked into tandems at all. What should I be looking at?
