Is this normal (height related)?
My boyfriend's younger sister is 15 and she's 5'10.
Her Mother is 5'2 and her Father is 5'7. Her sisters are 5'3 and 5'4 and her brother (my boyfriend) is 5'9.
I've honestly never heard of someone being hugely taller than their parents at such a young age. Apparently she's still growing too because last year, she was 5'8.5.
Oh and her Mother says she stopped growing at 21 and started growing at 12 just like this girl. So everyone is thinking she's gonna be 6'3 or something at age 21 as that's when her Mother stopped growing. Apparently she was average height when she was 11 and under but at 12, she started growing. She also got her period at the average age of 13 so there's nothing unusual there.
