Iam 15 years old, and i am 5'6. i started to grow earlier this year after i turned 15. now i am taller than my dad, mom, and big brother who is 5'4 and 17 years old. my brother and my dad are the same size, but they have bigger bodies. i am skinny and still have a small chest. will i still get taller in the future? i will be 16 by next month. will i stop growing? is this the size i will be for the rest of my life?
