I'm so sorry to hear this. I am having difficulties with my special needs kindergartner on the bus. He is really being picked on. For instance an older boy poured water on his lap, making it look as though my son had wet his pants. Something has happened twice within 3 days and they are not doing enough about it. It's not the same, but treatment of special needs children in public schools especially can be unjust. I hope you find justice and those teachers get a taste of their medicine. That is terribly unfair and just horrible! Good luck Mama!
