I realise I'm probably over thinking this as per bloody usual but DS is mentioning it more often.
He's 5 6" and not had a growth spurt yet, his voice hasn't broken, only a couple of rogue spots and no underarm hair.
He"s noticed his mates are maturing faster and getting taller than him. But he's just nudged up in height over the last year. He doesn't have a massive appetite and doesn't sleep in.
When did everyone else's teens grow?
