Hi, I'm new here and really just wanting some advice.
My son Daniel turned 13yrs in October last year, he always been tall but nothing concerning. I was curious in December as he seemed taller suddenly and his trainers were tight. He was measured at 6ft 1 and size 10 feet. Lately he's been more tired and says he aches. He plays rugby but only once a wk. Being curious again I measured him last night, he's now 6ft 3 and his size 10 trainers are too small.
So my question is, Should I been concerned at how quickly he's growing?
