Great job Mom on making that first big step and getting help from the state on his speech therapy. I was wondering if the SLP (Speech Language Pathologist), who should be coming to your house, has ever did a complete evaluation on your son, to diagnose the reason for his speech delay. Has she ever said it has Apraxia or something else? If you are not comfortable with the speech therapist that is coming to your house, you can and should request a new one.
If your son has been diagnosed with any type of speech delay, especially Apraxia, do not worry, he will talk. My son was diagnosed with Apraxia when he was two years old and could only say two words at the time. Now, at the age of 4, he tells us stories, it's wonderful. But it is a lot of hard work. You must work daily on his words and sounds. Does the speech therapist give him "homework" or specific words that he needs to study or work on? If not, ask why not. If there is a specific sound that she is working on with him, you need to be able to re-enforce that sound or word while she is not around, and without the re-enforcement, it will take him longer to progress. I noticed that you live in Pinellas County. I would contact your local school district and see if they have any type of program available through the school system that is in place just for children with speech delays. My son has attended a specific speech delayed class in our local public school for the past two years and it has done miracles for him.
Having a child with a speech delay is not the end of the world, it's just a different word that you must live in. It is a lot of hard work and a lot of different ways of doing every day things. Don't get me wrong, you can still a lot of fun with your son and still learn at the same time. You just learn to make every learning experience a game, and you will be amazed by his improvement.
If you have any questions, please feel free to contact me!
Have a great day!
