We went swimming today and I saw my DS has chest hair at 13. His voice broke at 12 and a half allnd he is 5' 5" do you think he will get taller, I hope he doesn't end up very short. There are lots of short and tall people in the family so it is hard to tell. DH is 5'10", I'm 5'5". My dad is 6'2" but my mum was 5'. L
