Let's stop a second, and take a breath - and more importantly, let's assume positive intent on the part of *everyone* involved.
As the parent of a disabled child, I can tell you - from 24 years of experience - that when your child is "different", you have to parent differently. No matter what anyone says. The reality is, that child has needs that are outside the "norm" and as their parent, you will have to try and meet those needs. In my case, I had one (bio) child (I'm blessed to have several "extra" kids who I love like my own, and who spend holidays with us, and who call us their family) and so I never had the opportunity to parent a "normal" or "regular" kid through childhood. I don't know what that looks like, or how it works. BUT, ask me anything about finding a car seat to fit a newborn infant with bilateral leg casts (hips to toes) or how to introduce your child - and her wheelchair - to her kindergarten class. Ask me about how to keep a suitcase packed for the *next* trip to the Shriner's Hospital - because we never, in her first 18 years, went more than 6 weeks between trips. Ask me about how to comfort a teenage girl who believed that no boy would ever love her because she was in a wheelchair. My experiences as a mother have been profoundly different from most other moms - and that's OK, because I know the truth... that "Normal" is just a setting on the washing machine.
It's NOT OK to assume that a parent that is trying to advocate for their child is simply being stubborn or selfish or unreasonable. They may not know, or be able to see, that their request is considered by the majority to be extreme; they only know that for the entire life of their child, they have had to advocate for everything. And so that is what they do. Is it "right"? Is it "fair"? That's not for us to judge. Instead, let's try to remember that they are trying to give their child the best possible experience they can. For their children, that means being able to ride the same ride over and over. The children that they are advocating for don't know that their parents are acting outside the bounds of "normalcy" when they ask for these special accommodations - they only know that they want to ride the ride again. You don't have to agree with their request of Disney, but at least try to understand *why* those parents are asking for these accommodations to be granted.
Let's all try to discuss this without casting aspersions on people we don't personally know. None of us wish to be judged unfairly by anyone - especially someone who doesn't know us, and doesn't know our entire story. And let's give that same grace to all of the parties involved in this legal action.
