From that link: > Gender is an essential characteristic of Heavenly Father’s plan of happiness. The intended meaning of gender in “The Family: A Proclamation to the World” is biological sex at birth. > Church leaders counsel against elective medical or surgical intervention for the purpose of attempting to transition to the opposite gender of a person’s birth sex (“sex reassignment”). Leaders advise that taking these actions will be cause for Church membership restrictions. > Leaders also counsel against social transitioning. A social transition includes changing dress or grooming, or changing a name or pronouns, to present oneself as other than his or her birth sex. Leaders advise that those who socially transition will experience some Church membership restrictions for the duration of this transition. Their advice on what treatments they support for transgender people is kind of vague and circumspect, but the gist seems to be "A therapist should at least be open to conversion therapy," which is generally considered harmful. Given the LDS Church's open campaign against gay rights based on the "The Family: A Proclamation to the World" (the same document referenced above), it seems reasonable to interpret this as stating opposition to transgender rights. Though as the parent noted, they are much less vocal on this topic.
