Our baby reached the typical development milestones, he even hit others earlier than expected, he kept his head up, sat, developed teeth, crawled, walked, mimicked and sang at the expected time. Everything was going accordingly for him, plus he even showed signs of intelligence for instance he would count to ten before he could speak. So I'd say everything developed perfectly up until he was 2 years old.
After a while we noticed that his speech wasn't developing at all and his interests had changed, especially after he started attending day-care. So when I started giving it attention, I noticed that he didn't want to hold eye contact for longer than a minute, he wouldn't respond to his name, he fixated on one thing, and he enjoyed his own company most of the time, but I also noticed that he was selective with his behavior patterns, sometimes he would be very social so much so that he'd interact with other kids from day-care enough to form friendships. But other days he'd prefer to play alone in the school yard, at a distance.
After a while of waiting for his speech to develop, we decided to take him to see a specialist. So, after a brief assessing, the Pediatrician confirmed what we had been suspecting for a while, she told us that our boy had mild regressive ASD and ADHD. We were left with so many questions.
The question we asked ourselves the most was what made him regress, we were told that there's no explanation of how one develops ASD but regression can be caused by either diet, abuse or simply the environment he's in. The therapist mentioned that our town has had a large number of ASD diagnostics recently so it must be something in the air 😅.
We then started the journey of trying to remediate the situation as there is no known cure for ASD. He is currently 5 years old and the situation has changed but not as much as we expected. His speech hasn't properly developed yet, he is social, he is potty training, he has improved holding eye contact and he is almost as independent as a typical todler can be. We're very proud of his progress and plan to work even harder to try getting him a close to normal life experience.
