Let me start by saying I have a child with Autism. I can't tell you unbelievably horrible things people have said. I find myself to be very patient with kids in lines because you never know. In my experiance it's adults that cause the most trouble.
That being said, I'm horrifyed at the attitudes of some of the people on this thread. I'd really like to meet some of you in real life, some of you are either very angry people that hate children or 'perfect' parents with 'perfect' children that need to 'teach the rest of the world how to behave'.
Every person with Autism is different and what works to control a situation once may or may not work again. For those of you that have issue with this, I'd suggest you change your mindset (since by CDC standards Autism could be considered 'epidemic' due to the stagering number of diagnosis) or stop leaving your house. Some of the things said of this thread are very ignorant. Kevin's parent is right we don't go to the store and ask for an autistic child, we are blessed to have them.
The rest of you (once again, general you) seem to have compassion and tolerance for people with different needs or issues. Thank you!
Now for my bad story(s). We were heading to TSM, I was pushing my youngest in a stroller (he was under 2yrs old). A 'wonderful' father was making a mad dash to get a FP and decided the best way to go was to jump my child in his stroller. For once, I had quick reflexes and jerked ds's stroller back so he missed kicking my 2 yr old in the head. Scared me and ds.
The same day, we were in line to see Lightning and Mater. A CM came up and said a Make a Wish family would be next, which was fine with us. The boy was so happy to see them it really was fun to see. The father behind us was pitching a fit, cussing in front of his kids and mine. After a few minutes, I'd had enough. I turned to him and said: "Sir, I'm sure that they would be happy to trade places with your family and not have a child that is possibly dying, please show some respect." At least he shut up.
We've had too many good stories to count. I'm very grateful, most of Disney's CM are wonderful, understanding people that see my child as I do and that she deserves the same chance to meet characters, trade pins, and enjoy all Disney has to offer. Thankfully, we run into some wonderful people that have spread

and we have passed out some pixie dust too. One of my fav memories was when my (at the time) 3 yr old ds saw a boy in a wheelchair and took one of his favorite pins off his lanyard and went and gave it to him. He made both moms cry in a good way
When it comes to kids, please be patient and nice, you have nothing lose by doing it but they have so much to gain by being shown compassion. You never know, they might belong to those parents screaming at each other that are falling down drunk.
