I am an intervention specialist
First of all, I am seriously not an expert, but I am typing down some of my thoughts. I'm sure someone else will have better advice. :)
I would document every discussion you have with individual students and with the whole class regarding this issue. Every time the teacher addresses it as well. Document what was done, what was said, and if there were any consequences. The parents obviously don't think you are doing enough, and perhaps they would see that something is being done. Also document any videos and/or visitors (counselors, etc) that you expose the kids to. After giving them the document - find out exactly WHAT MORE they expect you to do. Do they have any ideas for you and how you are supposed to handle the situation? If they say that they want someone punished for making an off hand comment, try to show them how unrealistic they are being.
The parents also need a definition of bullying: Dictionary dot com says a bully is:"a blustering, quarrelsome, overbearing person who habitually badgers and intimidates smaller or weaker people." Quite obviously, based on that definition, this child was not bullied by someone making an off hand comment about dogs. I found this nice website that might help as well....perhaps the parents should look at it. There is a checklist on there and comments like that are not on the list of bullying behaviors.http://www.stopbullyingnow.hrsa.gov/kids/what-is-bullying.aspx
Once they understand what bullying is, they need to understand that, if they expect everyone to let their child be who he/she is, then they should allow OTHER children to be who they are! It is OK for another child to think Dogs are ugly. It is also Ok for that child to express his/her opinion. Of course, getting this through their thick skulls will be the most difficult part. Unfortunately, I don't have any advice there....
Finally, some of what the child IS experiencing might be bullying. Don't discount everything that happens to this child as simply over-reacting. Each time is probably different, even if the majority of the incidents are simply "he made me feel bad" type stuff.
Wow! I've had some sensitive ones but the parents were usually trying to find a solution, not complaining and blaming the school.
I had some thoughts as I was reading. These are based on
Weird - the first thing that popped into my head was Munchausen by Proxy syndrome. Not that the parent is hurting the child for attention, but perhaps is encouraging the over-reaction for the attention SHE gets from the situation?
I have NO idea if this is what is going on, at all, but it struck me that this may be more about the parent than the child......
That crossed my mind also. I've seen some parents that get a thrill from being the savior, cooing, and doing the "Poor baby. Mommy's here' show. I'm not sure that is Munchausen's but it surely shows some type of issue. I've also had my share of staunch defenders with the perfect child who's issues were always someone else's fault.
