I'll guarantee your nephews parents HAVE NO CLUE you post his picture here and if they did and don't care then they are fucking dumb dicks.
Secondly, YOU'RE not that little adorable boys parent and shouldn't post it where you see fit
no shit, that's why i nor my wife have facebook because inevitably some asshole will ask us to post photos of our kids, which we agreed will never go online, at least until they're teens and can put them up themselves.
we also told our parents / their grandparents no kid photos anywhere online. it's an issue of right to privacy and protection of the kid.
besides , who would want to be associated with an admitted criminal / steroid user as an infant? just fucking stupid.
