He is 9.3 years and in Year 4. He is the smallest in his year and lots of younger kids are taller than him.
The regular pee taking is going on at school about him being small. He is popular, loads of friends, but it seems to be getting to him more than ever 
He is 4 feet tall (122 cms) and a size 12 shoe.
Dh was tinier than his peers till about 15 when he had a growth spurt so I keep telling ds the same will happen to him......
