Where I live ther eis something called Childfind, it's an early intervention program. Try to see if there is something like that in your area, you can take your child in and get them screened and if they qualify they can get special services. My son got free preschool b/c of his speech delays after age three. HE started to get services at about 18 months b/c of speech delays. My son did not start to talk until after age three. So I know what you are going through. Your pediatrican would probably know about some resources.
I'm very surprised that a speech therapist would note that he's progressing at a much slower than normal rate but "didn't need therapy". ??
I would call your local school and ask who they think is a good speech therapist and start again.
Best wishes.
I think that you should speak with another doctor, or be more specific about your concerns with your family doctor or your child's pediatrician. If you are concerned, do not ignore it. Mother's always know best. Be persistent and advocate for your son. My son was prenatally diagnosed with Down syndrome, and though the reason is different, we as parents may be facing some of the very same end result issues. Ask your doctor to line up all kinds of testing, and specialists. Take the stance that you want to prove that these diagnosis aren't the situation and the only way you can do this is to eliminate everything step by step. On the flip side of this, some children just do progress at different rates than others, and they may be typical as any other child. If in the end, you do discover that your son has been diagnosed with something (as you suspect may be Autism, or could even be Ashberger's syndrome - I only know a tiny bit about this one from a family member) you have the right to get the appropriate therapies for him, and the support you need to help him develop. Persevere and don't let one doctor stop you in your tracks. If in the end, it turns out that nothing is out of the ordinary, then you will have satisfied yourself and put your mind at ease. If you don't, you will continue to worry all the time that something could have been done earlier, should it turn out later that there was a missed diagnosis.
Good luck, and if you have any other questions that I can help you with, please feel free to message me directly.
