I am wondering the same thing.

As I'll have a 20 month age gap between #2 & #3, I figure a capsule will be a good investment as i want to be able to strap my 20 month old in the car before the newborn as he is likely to run away! I can keep the capsule in the trolley or on the ground until #2 is safely strapped in then pop the capsule in.

Just thinking whether it'll be worth buying one or hiring.
