Yes she’s done. It’s 2 years after first period, maybe a bit later than that if the period came before 12

Yes

Yes. Don’t they say two more years of height growth after first period. Then settle in!

Probably. She's above average

Almost certainly yes, done. Based on what you described.

DD14.5 (August birthday) hasn’t grown at all in the past year. Not in clothing or shoe size. She’s around 5’6” (we are both on the tall side) and wears a 7.5/8 shoe. She got her first period literally the week before she turned 11. I feel like I don’t remember growing in high school, but I can’t remember.
