Look at any case of “transgender” symptoms in children, and I can almost guarantee you that the situation has the same characteristics and family dynamics as a typical case of Münchausen syndrome.
It's more likely Munchausen by Proxy.

"Munchausen syndrome by proxy is a mental health disorder in which a caregiver, most often a mother, routinely makes up fake symptoms or causes real symptoms in a child or adult victim to make it appear that the victim has a true physical or mental health issue. These actions are typically a result of a maladaptive disorder or excessive attention-seeking by the caregiver. In addition to being a disorder, Munchausen syndrome by proxy is also considered a very serious form of child abuse."

"Hollywood actress Marcia Gay Harden went off on a "Drag isn't dangerous" telethon about the fact that ALL of her three children are "queer." Three kids and they ALL have abnormal sexual attractions? What are the chances of that happening?"
"What drives me is — my children are all queer," she added. "My eldest child is non-binary. My son is gay. My youngest is fluid. And you know, they are my kids and they teach me every day."
