oh wow....i understand that from a certain age on a child should not enter the opposite sex' rest- or locker-room. i also understand that 4-5 or maybe 6 years of age a child should be able to use these facilities by themselves...
but i also think that it's blown way out of proportion here. but of course i grew up in europe.
with liablity issues the way they are in the states i suppose it is an issue.
