My daughter said she wants to grow up to be like the girl from my strange addiction that ate Ajax. Should I be worried?

yes

Lol, I wouldn’t think too much of it. How old is she? Kids say silly things. Ask her why she would like to grow up to be like her. Maybe it’s not the fact that she ate Ajax, but perhaps she thought she was pretty or cool.

Just have a talk with her about why what the girl did was dangerous. It’s better to talk with her and have some open communication. I said a lot of crazy things growing up, and I idolized weird people. But that just being a kid. Parents help guide us through that strange stuff.
