p.s. I used to be into sheltering when DD was <5 but if they go to school it's better to take the attitude of allowing some exposure while developing a diaglog about what's in the culture and instilling your values, if they differ...for playdates and more time spent away at other's houses I am still picky about her close friends but in general the "dealing with it" philosophy has helped alot (me as well as her I think)
