My son is 12 he just began 6th grade and lately hes neen coming home making "period" jokes now the thing is he knows nothing about periods just that women have blood coming from somewhere, I dont like these jokes obviously but I know hes copying what he hears so would it be wrong for me to teach him all these woman things and proper words and meanings or should I let the school do it? Weve had the talk as far as puberty for males but nothing on females but definitely feel like I should..Opinions?
