I think you should call Child Protective Services (or whatever it's called in your area), and at least get some consult from them. Hopefully, the call will also create a file on your wife.
You also need to document this in the journal you are hopefully keeping, and let your attorney know right away.
THAT IS INEXCUSABLE, and TOTALLY UNACCEPTABLE. You need to tell her, in no uncertain terms, that if it happens again, you will call the police -- PERIOD.
