A 4 year old could not come up with something like this on her own.
That's what I'm thinking. She picked it up from her parents or another adult of influence.
All the “atta boys” she is getting are the real reason this girl is saying she’s a boy. She wants the love and acceptance of the adults around her. How sad that she has to pretzel herself, deny the sex expressed in every cell of her body to get people to cheer for her. What a destructive response by the adults cheering her on to self mutilation and a lifetime of pain & mutilation. They are anathema.
