so, my son's uncle is 3.5 years old.
and every single time they play together, he hits my son on the head with a toy or something...
His parents give him time-outs or wtv. but it doesn't work, he literately will go hit my son again 1 min later
So he smacked my son today, and I smacked him.  
this caused a bit of a fuse.... ya sure its not my kid and i shouldn't be disciplining him.... wtv... i got mad he got smacked, big deal.
its been like a year we keep explaining to him that what he's doing is "not nice" I'm fed up.
if it was my kid always hitting a smaller kid, I'd smack him!
