She’s the dancer, right? Does she do a lot of gymnastics? It really does stunt your growth, among other things. My sis had to go on birth control to start her menstrual cycle because her activity level prevented it to happen naturally. I remember my mom being so upset over it.. but it had to be done, she was getting shin splints or something due to her hormones being out of whack.
Her activity level also caused problems with the ability to get pregnant a few years ago, she had to cut back.
This is one of the reasons I won’t allow my kid to spend all of his time on one sport.. I had a cousin who was off the charts tall during elementary school, he was a star basketball player.. made varsity his freshman year of high school.. and then- everyone had growth spurts, and he did not. Ended up being ‘average height’ in adulthood, not tall. Definitely didn’t help him with basketball.
Kids grow at all different times!
