Three kids who are to young to know right now
We have three kids 4 year old daughter, 1.5 year old son and 4 month old daughter. I have no intentions of telling them when they get older. When our oldest was born, I reduced the amount of clothing I had and kept only items that could be passed off as my wifes. (Wife is fully supportive). My oldest has seen me dressed, but I was only wearing jeans and a tee shirt at the time so to her, it shouldn't have looked any different than my male jeans and tee shirts.
