My name is Meredith Eaton. I am 12 years old and have SPD and ADHD. First of all your site has provided the most info I have gotten on this topic.
I also have a question, My little angel of a sister Siobhan always gets so aggravated when I ask her to stop some specific noises that she makes (sniffiling, tapping, kicking my seat, popping sounds with her lips etc.) I don't just ask her to please stop, I always try to find a way to ask nicely if my mom or dad could get a tissue or glass of water. They never get angry, but my sister gets EXTREMELY angry. She knows that I have SPD and ADHD but she keeps on doing it.
Do you have any ideas on how to have her understand how annoying it is to me?
