Exactly! Use the tools at your disposal to have the best possible trip - whatever they are - and don't give a moment's thought to what anyone else thinks. To be honest, most other Guests are so wrapped up in their own vacation that they won't even notice your family - and if they do, so what? I make eye contact, smile the biggest smile I have, give them a cheery wave, and go on.
You are doing an awesome job! Kids don't come with an instruction manual to begin with, and when our kids are different, it can be a struggle to identify exactly what we need to do to support them the best. (((hugs))) I hope that you and your family have the most Magical trip possible!
