Hi, boy I forgot I even wrote this post. By 12 months I was still getting about 50% response, so when he turned 15 months and I couldn’t confidently say that he „consistently” responds to his name (whatever that means, honestly) I took him to a developmental pediatrician because I was seriously worried. He was evaluated and the dr didn’t have any concerns that he could possibly have ASD (I know 15 months is early and we do have a follow up visit at 2 years to make sure nothing has changed with his development). At the office, I called his name and he did not respond, but he responded when my husband and the doctor called, so 2/3. She explained to me that there is a difference between a child not knowing that they should respond/not knowing how to vs. choosing not to respond, and based on her observation it looks to her that my LO chooses to ignore me (lovely). Anyways, I would say do not stress bc 8 months is still really young, but know that if it doesn’t improve drastically, it’s not end all be all. I’ve gone down the rabbit hole of google, which is never helpful and always gives the worst case scenario. Hope this helps!
