Any growing tips that actually work?

I wish. I'm 53 and 5 foot and nothing I did helped me and I did all the right things throughout my life. Height is mainly genetic, it just depends on which side of the coin you drop. My sister is tall but she came from my mother's side who were tall whereas I'm from my father's side who were all short. What will be will be and there's nothing you can do about it sadly.

just select better parents

milk?

sleep?

drastic measures include breaking one's bones and re-attaching them but i would consult a medical physician first

Probably exercise more, but if ur growth plates have closed, there's not much u can do
