When they judge my kid

I think the worst thing of all is seeing people judge the special needs and ADD kids in my life. Teachers or friends and even family who say Oh he's just lazy or he is just undisciplined. Its like they refuse to see a disability they want to just assume that you're a bad kid. I went through this growing up and it hurt so much to be told that I was a naughty little girl for things that I couldn't control or understand. I don't want that for my kids or my nephew. Its crippling emotionally to grow up being treated like you're a bad kid for not being normal or prefect. It gets the momma bear in me going and then I am too upset and angry to respond properly. Every school year am I going to have to educate another teacher? How do you get it into people's heads that this is a disability and not choosing to be naughty?
