"Hi, I'm Biju C and I'm father to two boys, 7 and 4 respectively. Is there a 12-step programme to restore my sanity after such trauma?"
Yes; it's called "grandparenthood". There are many opportunities for fun, from feeding the grandchildren sugar just before bedtime to giving them drums.
It was one of my father's great regrets that I never had children so that he could exact his well-deserved revenge for my childhood.
Cheers, Bruce
