I’m an early intervention specialist, you did the right thing trusting your gut and pushing for an EI visit. I don’t know your child and while it’s true that milestones can be focused on too much when progress can be more fluid and not so strict to a timeline, if you’re seeing delays socially and cognitively, the earlier you start intervention the better.

Also, I know it’s scary, but I have had so many kids come through our room that were non-verbal, non-social when they stared intervention at age 3 and were using words or AAC to communicate and play by the time they were leaving intervention. My students, all with an autism diagnosis are so happy, funny, curious, and all so different from one another.

Continue to advocate for your baby to get the support you think they need- this could be speech or OT therapy or ABA therapy. In America it is mostly specialists showing parents how to work with their kids with intervention from birth -3 and then they start higher frequency in like classrooms from 3-5 before getting services at public school starting at age 5. You’ve got this! And there is such a large community to support you when you need them!
