Kinder Care/ ASA

This was Bea's first week in the Kinder Care/ASA program.  This is what happened...

Tuesday: She tells me this boy was being mean to her. Calling her ugly and saying that he hates her.
(I chalked it up to her being the new kid in the program.)

Wednesday: She still spoke about the kid being mean but she was able to ignore it for the most part.

Thursday: This kid stabbed her in the arm with a blue marker. And continued to be mean to her.
(I told her maybe he likes her and doesn't know how to express it.)

Friday: I picked her up early. I whispered to her if the kid was there today. She whispered back where he was and as I was looking up from signing her out I saw him... I then looked down to finish signing out and he chucked a chalkboard eraser at me! Either that or he was aiming for Bea. There was a girl working there on the floor and she said: "LUKE!" and the gal next to me didn't say anything... maybe she didn't see it? Bea bent down and picked up the eraser and walked it over to the board and said: "No thank you Luke." While I was a bit dumbfounded and just said: "Wow. That was rude."

I promptly called my mom to see what my rights were. Since it's not a school program I couldn't contact the principal. So I called the supervisor through parks and recreation and filed a complaint.  He was going to speak to the girls working and then speak to the mom... He called me back, but I missed his call!!

I don't know what to do! I want to take her out... but then I don't want to be all cowardly and have this be a regular thing in her life. "So and so is being mean to me..."  "Okay, time to move to a different school..."

Help!
