OK here goes, Aka (waiting for your contribution too)
The chance to change endless dirty nappies
Discovering regurgitated milk on the back of your jumper
Being interested in endless games of snakes and ladders
Ditto for jigsaw puzzles, complicated 'bored' games, marble runs - and retrieving marbles - and matching games.
Reading endless stories
Wiping snotty noses
Shortening school trousers, sewing name tapes into uniform
Answering endless questions
Resolving disputes
And not being awarded a GBG (great British grandparent)
