My son was diagnosed with a sensory processing disorder and a speech delay, and would get really excited and it was almost impossible to calm him down. His therapist had him try a weighted vest that did absolutely nothing for him and while she did give us techniques to help, it was very overwhelming at times. Then we tried compression clothing and it worked a little bit nothing really noticeable. She then brought this vest(but in a bigger size) and the change was amazing. It was like he could “see”(he’s not blind nor does he have vision problems) for the first time. Tasks that normally would be challenging for him were now manageable. He could focus on us and what we were asking him. He could slow down and speak clearly and put sentences together that he never could before. So we bought him one in his size for home and school use. Now it’s not a miracle, he still gets excited, he still gets overstimulated and his speech is still a work in progress, but the vest helps him to calm down on his own and helps him regulate his emotions much better. With weekly therapy, using the vest for those times he gets overstimulated, and using the techniques his therapist helped us with, he is doing SO much better. He is using the vest less now because he is starting to recognize when he gets overstimulated and asks for the vest himself when he feels he is getting to that point. I would definitely recommend this.
