There seems to be an assumption that we would just turn our son loose in the restaurant and let him run wherever he wanted.
Um, no. We're not that dense.
But he does need to get up and stim often. It's not running around and screaming, it's normally walking around and scripting (his favorite thing to script is Mickey Mouse Clubhouse by the way), and either myself or my husband is always in tow.
So, thanks to those who had supportive advice.
To those who said not to subject other diners to our son, I've learned enough on my journey with Autism to let those comments slide. He's a human being. We're his family. We deserve a Disney Vacation just like the rest of you. I've learned to really not give a crap who our son makes uncomfortable. That's their problem.
