Congratulations to the proud parents (and grandparents,) from us downunder!
Grandchildren are more fun than your own kids actually...they're all care and no responsibility.
It soiled its diaper?
No problem!
Just give it back!

And when they're older, and bouncing off the floor/wall/ceiling because you fed them up on candy...no problem!
Just give it back!

They're great fun; you've got more time to spend with them than you had with your own...back then you were too busy working to pay the bills...

Enjoy him mate!

(...and spoil him rotten... )
