See, I come at this from a different perspective. I was teased and bullied mercilessly throughout my school career. Then my daughter came along and she was one of those children "born with reasons for people to stare or ridicule them". She had a large, complicated haemangioma, dragging her upper lip down over her mouth.
After much research and discussion with doctors, we opted for a "wait and see" approach, rather than radical surgery to "normalize" her. Back home, we got a LOT of flack from people who thought that we were setting her up for bullying. They couldn't understand why we wouldn't do everything in our power to make her look normal.
But I'm sorry - that doesn't fly with me. I suffered that abuse, and I was a perfectly ordinary looking little girl. I figured any daughter of mine would naturally have to deal with stupid people, just like I did, and what her face looked like wouldn't make one bit of difference.
I loved my beautiful baby. I kissed her birthmark, along with every other part of her. I taught her to say, "This is my nose, these are my toes, this is my birthmark..." When she was old enough and people said, "Ew, what's wrong with your face?" I taught her to say, "That's a strawberry birthmark, I was born with it!" Then whenever people asked ME, I'd turn to her and say, "Honey, you want to answer this?"
Eventually she did choose to have one surgery and some laser treatments, which made her beautiful smile more visible.

But ultimately she's chosen not to have any further work done. She says, "It's part of me. I'm happy with who I am."
And so am I!
So yeah... I warned my little boy of the potential consequences of wearing a princess dress. But I also made it clear that it was HIS choice, and I'd have supported him a hundred percent. Because no matter what you do in life, stupid people WILL say stupid things. And I'm not going to let stupid people dictate my choices, or my children's choices.
We're stronger than that!
