I am far too old to remember even if Mother would let us - but I do remember pulling my twin round on a cart Father built because why should she bother walking when I could do it for her?!!!!
Ah yes, I can remember that - and doing it with my own son too! And being carried on my father's shoulders. Little Chico often stands on my feet (well, anybody's feet will do, he's not fussy) - I'll have to have a go walking when he's on and see if he stays! He also stands on the backs of the other two when they're lying down and I often wonder whether he'd stay on if they stood up!
