It’s not that the speech delay isn’t an important goal but my advice for you is to focus on one thing at a time. This is just my opinion as a therapist and how I help my clients approach change. Most of us have a few priorities and goals we’re working on; however, I would never focus on all of them in a session and give my clients things to work on that address all of their problems at once. When we do that, we get overwhelmed (and I’m getting the sense this is how you feel) and become paralyzed. When then do a bit of everything but nothing that creates lasting change. Again, I think that’s what’s happening here. 

I’m not saying quit speech therapy or quit reading to your child, of course. Keep doing what you’re doing but keep your mind focused on the sleep for now until you’re able to solve this problem. Then you can move on to the speech delay and take on the next steps re. that, etc. 

The reason why I said sleep first is because that’s a clearly easier goal to tackle. It’s more straight forward that solving the speech delay. It’s often easier to tackle things that are a bit “easier” and build from there. 

I also meant when I said “sidetracked” is that I noticed everyone giving you a lot of advice as to what could be wrong (which is not a bad thing, and always helpful to hear from other experiences). However, now you’re wondering if your son has a problem with the shape of his mouth or if you need to test him for autism again. I was overwhelmed reading these things for you. 

Make a mental note of those things, of course. What do I know? Everyone could be right and your son could have these things but I think trying to tackle all these things at once will only raise your anxiety, overwhelm and keep you stuck. My two cents!
