Scary and more annoying than anything for sure. As if we didn't put up with enough on a daily basis. The fact the child's behaviour is out of control at school too will certainly help in your favour. As far as the shirt goes and the scratches both are normal play/tantrum reactions. Child could have done it himself in frustration and there is no way for anyone to prove otherwise. A scratch is not considered abuse by anyone unless it happens on a consistent basis. Basically the parents don't have a lot to go on and doubtful a lawyer would procede with anything since it is all based on heresay and no facts.

They may very well call authorities and you may get a call or visit in due course but it won't be considered an emergency so it may take awhile. It really is nothing to worry about since they simply come, visit the daycare, talk to you. This is a good time to talk about the child's behaviour in general, school complaints, etc. the parent may not have made them aware of.

The good that might come out of this is that the child/family will get some help in dealing with the child's anger issues and lack of social skills.

But for now do nothing. Print out the email from the parent so you have a hard copy just in case something happens to your computer but do not delete the email from your computer.
