How do i convince my parents to get me Fme or expansion while still growing

[aritr]

I’m 14 and have been looking into maxillary expansion/ infra recession fixes,(might be cope). The more i look into it the more i feel like waiting till im older is a bad idea.

Why i think i need it -
I am pretty positive I have a narrow palate (palate is more v shaped and not as wide as compared to regular palates)

I can only breathe through one nostril at a time. It switches off daily, and even if i’m able to breathe through one nostril, it still is uncomfortable to do so.

What I really want it to expand my maxilla, plus get good forward growth. And i’m curious if this would fix my recessed infras ?

The thing is anytime I bring up something around my face bones they say that they’ll just grow during puberty, but I’m already halfway through.

Also, would it be good to do face mask + Fme/Marpe

MARPE would work even as you get older from what I know, although it isn't guaranteed that your infraorbital recession would substantially disappear after
