I'll tell u an easy way...

Whenever u go to any place for eg malls or at a friends house... when u c a kid.. spend some time with them.. let him c u playing with the kid... let him c u adorning the kid... and pass some poking comments like " i wish i had a baby like this". let him hear that...
when u leave the kid.. just act as though ur not able leave the kid...
try this for sometime...
And if he really loves.... He'll give u what u want

Hows that!!!
