My 3 1/2 year old has level three autism and this was one of the best purchases I’ve ever made. Any time she has a meltdown I put her in the swing with the lights and it truly works like magic. She does tend to fall down the sides of the blow up pillow they provide, but we just put a small pillow behind and it’s fine! I urge anyone who knows a child with autism to get one of these for them because it has become a staple in our home
