How to get two kids in a stroller designed for one..

I originally bought my stroller, Peg Perego Pliko 3 Classico, for the little rubberized step in the back which, in Europe, it is promoted as a step for the second child to stand onto. In America, they do not promote it as such - I do not know why!

This is the position for two children, sanctioned by the manufacturer..

We have come up with a couple more of our own.
