D.G.
I understand exactly what you are going through. My son, who was 3 in novemeber also has apraxia. He talks on about a 19 month old level. He has a ton of apraximations, but very few real words. I understand him better then anyone but most people have no clue what he is saying.
I worry all the time about him making friends and the struggles he has ahead. He has a ton of therapy which makes having play dates tough, I think you said it best...it is heart breaking to watch your child have to struggle with anything let alone something that comes so naturally to all his peers. I cry when I hear my friends complain about how their kids talk all the time and are never quite. My son has yet to really say MaMa and very few people truly get how that feels.
There is hope. With prompt speech therapy most of these kids will talk and catch up with their peers. hang in there!!! there is a light at the end of the tunnel. I have started support groups for children with special needs in my son's school. It is so helpful to be around other moms who get the struggles and are there to listen to my fears., All the kids have different issues but we are all there for each other. Try starting the same thing at your child's school.
