"It's OK to be Neither" 
This is a wonderful article written by a 1st grade teacher in Milwaukee, Wisconsin about how she taught the concept of gender to her class and about how some early education can help children become more accepting of gender variance in our society.
It also links so some great books about being different and breaking down gender norms that are for young children!
What do you folks think about teaching young children about gender?
Wonderful story, if you have time, everyone should read it!
