Eating hair and feeling depleted

I haven't been blogging much out of sheer exhaustion. I seemed to really crash after Polly's first surgery, to rally again, to start to focus on all the aspects of our lives instead of just brain surgery, all the while knowing the next surgery is looming and my attempts at catching up just aren't happening.

But my question today is about Evie. She likes to eat hair and now that her hair is growing out a bit she is eating her own. As it is she walks around with a chew tube necklace for her oral fixation and that has helped a bit. Just wondering what you would do? I want her hair to grow...it's so pretty. It's not long enough to pull back.

But I don't want her to eat it.

Although it means she is pulling everyone else's hair a lot less these days.

Ideas?
