The child has no illness, physical or otherwise. HE is a boy, and his mother belongs in a psych ward.
I respect children. If tiny kids feel like the gender they weren’t born, they are telling the truth. It appears to be a brain anomaly. It can’t be fun. You probably feel very “wrong.” But Gd doesn’t make mistakes. We need to find what causes this and we need to love all people born with differences. Compassion and cure/prevention.
