I have autism concerns about my little boy who just turned 22 months, and I'm wondering if anyone has experienced this/has any advice. He is such a sweet boy, gentle and easygoing, yet incredibly active (always moving/climbing). He has a definte speech delay. At his two year check up he could follow directions, point to nose, put hands up high, wave etc, but was barely talking outside of dada/hiya etc. He had a sudden explosion of speech a few weeks ago, colours, numbers, alphabet, is saying short phrases "bye bye dada" "what is that" etc. Babbles a lot. This week we realised that he has visually learned all of the alphabet. We've tested it and he can get all the letters, even out of order. At first we were thrilled, now I'm really nervous. With the speech delay, extreme activity levels, and now i'm seeing an autism sign referring to obsessive alphabet repetition called hyperlexia. When he was around 1 we would go to a local playground that had giant indented letters indented and all he wanted to do is trace them with his fingers while I said the sounds. He is only two so he largely plays independely though is interacting with his sibling/loves chasing her/being chased. He doesn't avoid eye contact, and can be snuggly when he finally stops moving. I feel like so much of this is unknown and only time will tell, and I probably sound overly anxious. He is "functioning" and our friends said their son was the same and knew letters at the same age, and isn't autistic but is now a gifted child in a specialist school due to academic abilities. We are starting a new daycare this week due to his speech delay, at the recommendation of his doctor, so they might be able to assess/watch for warning signs. I guess I'm just a bit lost now at where we go from here. If anyone has experienced this, I'd love to know aboubt your child and how things worked out long term/any advice you have.
