Parents, I'm talking from personal experience, don't invalidate your child if they come out to you. I just came out to my mom as asexual and her first reaction was, "No you're not. You're still young and those senses develop over time. Plus, asexuality does not exist. It's just society trying to shove a label down your throat. Every human being is born with pheromones."
Do you know how soul-crushing that is to a child? To be denied a label that you discovered yourself and took a lot of self-exploration in order to confirm? I'm just glad that I didn't tell her the other parts of my identity.
My point is, if your child comes out to you, try to accept them. There is literally no harm in trying. And if it turns out they were wrong later, they were wrong. Remember that they are your child and they trust you a lot in order to come out to you. Just try to hear them out.
