I hate that your children have, or may have, Asperger's Syndrome, but it is nice to know that other parents out there understand they day-to-day struggle raising a child with a disorder. I am a single/divorced mom and have raised my daughter by myself (with the exception of a very brief interim marriage) for 10 years.
After all the hassle I have had with this school for 5 years over my daughter, I have returned to school to pursue a degree as a School Psychology Specialist with an emphasis in autism/asperger's. If you can't beat them, join them. I can't change them from out here, so I will get on the inside and work from the inside out to bring awareness to at least one school district about this disorder.
Because our children look so normal, many people just assume they are "bad" kids or have behavioral problems when they don't. I just wish someone, somewhere in this country would raise public awareness of this disorder so our children do not suffer so much.
My daughter had such a difficult time last year, even with her teacher, that I pulled her from school the last two weeks and wrote a six page letter to the school principal and assistant principal letting them know that they had egregiously violated my daughter's civil rights (I also named specific teachers' names in the letter who had mistreated my child) and I was calling my state's attorney general, the state Department of Ed. and DHS. I was amazed at how quickly they were calling me, wanting me to come to the school to talk things over and get an IEP in place for my daughter that should have been there in 2003, even with the incorrect diagnosis. There is, of course, background info I haven't listed here. The point is, I let them know in no uncertain terms exactly what they had done and that I was not putting up with it. They had allowed my daughter to be bullied all year, even by the teacher, and then when she got fed up and struck back, they saw her because she wasn't as crafty as her tormentors, who kept their behavior under the radar. As a result, I was called to the school because the assistant principal threatened to expel her. When I found out what had really been happening, that is when I pulled her from school, wrote the letter and called the agencies.
DO NOT LET THEM RUN OVER YOU. Schools will threaten and try their best to intimidate you into doing what they want, and they usually get away with it. Human nature is human nature: Intimidation works for them, so they keep doing it. Find out what your child's rights are (look at IDEA and FAPE and whatever state provisions you may have) and put it in writing to the school that you are not going to be quiet and they are not going to get away with unconscionable violations of your child's rights.
Be careful in choosing your battles, though. If it isn't really worth fussing about, don't. When you become the mother who is at the school every day complaining about something, they will not take you as seriously. It is like the "nagging wife" syndrome and gets you nowhere fast and certainly doesn't help your child.
BTW, check out the OASIS website, if you haven't already. It is a great online support for AS parents specifically and you can pick up some great information from the parents.
Wish all of you the best!
