In 6th-7th grade I was taller than my friends and I was 5'6 at the time. After two years, they grew 3-4 inches taller than me.
Also, I'm 5'7 or 5'8 right now and I've had the same height since the end of my 7th grade year coming into 8th grade. I'm a freshman in hs and currently 15 y/o. Is it possible that I still haven't reached my growth spurt?
Mom- 5'3
Dad- 5'6
^ if that helps
