Yes - I do believe that jealousy is a part of her hitting the little boy in the first place (doesn't this all sound so silly?).

I am curious as to why cina is recommended - it is a remedy that I am not that familiar with.

Arsenicum sounds like a possibility - I will read up on it some more when nap time rolls around.

Thank you everyone - I will post later with any progress.
