I had my first child before I was a Christian, and I had some weird ideas about letting my son be exposed to all kinds of toys. Gender neutral/boys/ girls. Other than LEGO all he wanted to do was play with guns.
I was against guns, so he would make them out of LEGO. So I forbid that, and he would find sticks that looked like guns and shoot them when he thought I wasn't looking. I finally gave up when he was 5, about the same time I became a Christian. When he got into high school, he joined the Reserve. Became a "gunner." Yes, I learned my lesson!
I still had the toys when my next 2 sons grew up. The second son wanted sports, sports, and nothing but sports. When he was 3, I finally broke down and bought him a small hockey stick, and a net. He wore the stick to nothing playing street hockey. The last thing I wanted was to be a hockey mom, but figured my sons should learn how to skate. The rest is history. Both sons played Major Junior, 1 went to university on a hockey scholarship, the other went pro for 10 years, played Tier 2 and in Europe and is a Pro Hockey Coach. As for the dolls, they bashed their heads in, and generally mocked the girl toys.
I finally had a girl, and she started skating at age 3. I put her in a ringette, boys hockey and figure skating. She could out skate everyone. But she hated playing with the boys, (because they smell) and Ringette didn't have a Rep team for 5 year olds. All she wanted to do was figure skate. I finally let her only figure skate 6 days a week, and she got all her Golds, Diamond Dances, Novice Competitive, and her figure skating certificate. Skated provincially, competitively up time provincial level. She put herself through university coaching figure skating. She loved her girly toys, and always wore a dress, even when she was small, to differentiate herself from her 3 brothers.
Which is a long way to say, I think if you are sensitive to your children, they will do what they want. I'm not saying there aren't effeminate men, or masculine women, but they don't need to resort to chemicals, hormones and surgery, if the parents are sensitive, they should be able to bring out the gifts and talents of every child, regardless of gender, but also because of gender.
My daughter had a wonderful opportunity to grow up to play women's hockey, and no chance of becoming a figure skating medalist in the Olympics. But, she was naturally feminine and followed both what she saw a woman is, and what society says. Same with my boys. They could not be more masculine, it was nothing my husband and I did. True we were normal, heterosexual parents, and followed roles, because that is what we knew how to do.
It is abuse to administer chemicals and perform surgery on children which permanently disfigures them. No child should be experimented on. Counseling, finding their strengths, and love are all tools that should be used to help kids find that they are the gender their bodies say they are!
