When he gets upset and angry (often!) he will sometimes pull out handfuls of his hair, a worrying amount! There's one patch where all the hairs are really short due to this.
What can I do? I obviously stop him when I see it and have to wrench his death grip of his hair but I can't always stop him in time. It's only started in the last week, he'd never done it before them. He's (just) 2.
Please help
