One of my favorite resources to help families who are dealing with Sensory Processing Disorder is A Sensory Life, created by Angie Voss. I've worked with a lot of kids who have difficulties with sensory input, and this website had a wealth of information for parents whose kids struggle with sensory issues.
Have you ever been at a busy playground surrounded by children moving in all sorts of different directions? As a mom of two, I often find myself there. And every time, it always strikes me as beautiful chaos. The cacophony of voices and the constant movement. All you see is children running, almost in a blur.
