Hi C.,
My 7 year old daughter has a sensory integration disorder. She has not been 'officially' diagnosed but it is apparent. From the moment she was born, she was sensitive to her enviornment. Loud noises, the feel of clothes, getting her nails trimmed...all were challenges. Like the other Moms who responded, I vacuum when she is outside (her Dad would take her when she was little, now she goes in the backyard with her sister). We cut all the tags out of clothes. Clothes and shoe shopping is a MAJOR ordeal. I have to summon all of my patience to do it. We usually have to go to 5 or 6 stores to find one pair of shoes that will be okay. She tries on every article of clothing before we buy it because I am tired of wasting money on clothes she won't wear because there is an applique or seam that bothers her. I feel bad for her because there are times she desperately wants a certain piece of clothing (a shirt with Hello Kitty or something) but when she tries it on, she can tell immediately that it doesn't feel right. For birthday parties, we couldn't sing "Happy Birthday" to her for the first couple years because it was too loud and she would end up in tears. For attending events, I found that if we were the first to arrive, she would do much better because she would have time to orient herself. Team sports were a nightmare and we won't go there again for a few years. Try sports like swimming, dancing or hiking. I did read "The Highly Sensitive Child" and found it a little depressing. If I had to do it all over again, I would have taken her to an Occupational Therapist when she was young. Apparently there is a brush therapy they do to help develop the skin touch sensors.
Good luck and feel free to email me with questions,
E.
