Early intervention is a good thing. It can help him develop those skills and help you understand how best to help him. But if they do diagnose him with anything, I would make sure it doesn't become a crutch. I know people who are autistic and incredibly functional but would rather use it as a crutch. As someone who's not officially diagnosed, but many teachers and counselors suspected I am, but my parents didn't believe I needed the diagnosis, it's frustrating as hell to see it used as a crutch. I do wish I was diagnosed as a kid though, it probably would've been beneficial, but as an adult, I don't see the point now.
Hi, if you’re at all concerned I’d bring it up to his pediatrician so they can do a speech/language evaluation. Even if it’s just for a peace of mind. I had my 2 year old evaluated because I had concerns, but he ended up score above average on the evaluation. He’s 3 now & doing well. Most of the time, it just depends on the child, each develop at their own pace. My daughter is an opposite of my son. I think girls language skills develop first.
