My ds5 has a massive head.

I have his hair cut in a particular way to minimise it.

His statistics are:

Height: below 0.04th percentile

Head: 90th percentile!

Clothes size, age two

Hat size, age five or six. Often more.

When he was weaned the health visitor noted that he had dropped off the charts and sent him to a london teaching hospital to investigate why he was so tiny. They tested him for all sorts, including a scary few months looking at cystic fibrosis. They noted then that he had an enormous head. It is especially large over his ears!
