I'll try to keep this short for once.
You have your first child and they are the love of your life (You choose which sex, whichever you would want first). At age five you realize that your child prefers playing with toys that are generally played with by the opposite sex more than the toys that are generally played with by their sex (ie: trucks for boys and dolls for girls). Do you do anything? At age eight, your child tells you that they are the opposite sex, nonchalantly, of course, because they're still a kid. Do you do anything? At age 10 your child begins to dress and act like the opposite sex. What do you do? At age 12 your child tells you that they want to take hormones and have a sex-change procedure done. What do you do? Would you be embarrassed of your child's behavior in front of long-time friends or in public?
