That has to be most stupidest thing i have ever read about. i would never do that and i have done stupid things like drink with my house mate on the roof of our old house and get drunk then have to climb down back to the ground drunk.
I recall a news item about some mother who'd taken her kid on a boat trip to watch sharks attacking a whale carcass. She stepped off the boat with the kid, onto the carcass so it could get a better look.
FFS what's ,wrong with just selling the kids if you want rid of them? Why drag Mother Nature into it?
