I used to have a skin tag on my nipple, it looked like a third nipple. I tried to get out of changing in front of others, but they made me. Merciless bullying ensued, it was already pretty bad because of neurodivergence differences. My home life was abusive so I never got a break. If this were still a thing, I would do everything I could to prevent it from happening to my kids. People got bullied about birthmarks, baby fat, you know how kids are, any excuse. That is not an environment to throw vulnerable children into.
