Oh, they have done your son a terrible dis-service. I'm a pediatric PT who has worked with many kids who also received speech therapy, and know many wonderful speech therapists. To start, age 1 is too soon for a speech therapy evaluation. Most won't even test a child until age 2, so that evaluation could very well be inaccurate. Second, SO many kids are falsely labeled with autism. If you believe, either correctly or not, that he doesn't have it, it is your right and your job as a parent to seek out a second opinion by a "developmental pediatrician" or other expert. If you believe he might be tongue-tied, that is a very legitimate concern. Have you mentioned this to his pediatrician? If you aren't happy with his previous assessment, try a new pediatrician or see if yours will refer you to an ear/nose/throat (ENT) Dr. Regardless of the cause, it is obvious that your son is delayed quite a bit and should have been receiving early intervention, which is free until age 3 and then passed on to the school district. If you contact the Special Education Dept. of your local school dist. they should help you with the process. This does not mean he will be in special education classes, but that is the dept. that handles therapists. My son was a late talker, but kids who simply talk late and don't have any other issues generally catch up quickly. A few months after saying his first words, my son was speaking in long sentences. Your son needs some help to catch up and I hope you can find the right person to help you on your way! Best of luck!!!
