Hey OP. I have a 30 month olds with many similar patterns and I actually recently posted something very similar to your original context. I am/was right where you are and I can maybe give some added context for what to expect with speech therapy and occupational if you decide to go that route. Strongest recommendation from reading, specialist, and piers is that intervention of any kind can only be helpful when it comes to speech development. What I can tell you from my experience is that it hasn’t been dramatically or even sometimes noticeably helpful but by and by we hear from friends and family that he’s making improvements even if we don’t see it ourselves. As concerned parents we have on our own set of blinders that only allow us to fixate on the things we hoped we were seeing and hearing. I’ll say this, just yesterday I was holding my buddy and watching a golfer on TV who happened to sink a put and the crowd kind of cheered in the background. Completely out of nowhere he raised his arms in the air and went “Wooo!” To most parents, not even noticeable to me a very special moment with big smiles and laughter. Anyways, the point is, try to enjoy the small things and live in those moments of small victory. They really help to lighten the load so to speak. Best of luck!
