She ate human feces?

used to babysit for my friend. Well, everytime I babysat, her eldest daughter (about 5) used to eat her own feces regularly.
She has since stopped, but I never told the mum in case she thought I was a bad friend. Anyway, it was about 2 or 3 years ago now...But I'm worried her daughter will die. Please help!
These are the facts:
It was her own poo, and it was regular
She was only young
She never got ill from it
She stopped now
It was 2-3 years ago.
Will she get E-Coli, or hepatitus (hepatitis)? Is she gonna be OK?
Is she OK mentally? She's stopped now and told me that she knows it was wrong and is ashamed. But she's got friends, a social life...etc. So will she be OK, and is her mental health alright? I mean, she seems normal now. Did she have Pica?

You should speak with her parent(s) about this so that it is no longer a secret between you and the girl. It is clearly still bothering you, and it is not right for you to collude with this girl in keeping the secret. She's not now going to be hurt by what happened, so you don't have to be worried about that. Your sense that you would be viewed as a 'bad friend' by reporting what happended is a mistake - friends report what happended so their parents will be well informed about their own children.
