Has anyone used Audioblox for a preschooler? My 5 yr old son has communication and processing problems. Although I homeschool my other 3, he is in special ed. nursery school. He receives speech, OT and PT. I would like to bring him home as soon as possible, but he still needs a lot of services. I read the info on the Audioblox site and it sounded intriguing, but I would like to hear from someone who has used it with a little one. Thanks for your help.
