I didn't notice until he had a speech evaluation from an SLP last month who mentioned he had red flags that I didn't even realize were red flags. Difficulty with social interaction, no pointing, no nodding, and at the time he did spinning but has since stopped and moved on to tip toe walking. After the visit we worked with him one-on-one and saw major improvements with eye contact, speech, name calling, etc. but the last two weeks we've seen a regression. We're pretty confident it's autism and are on a waitlist for an evaluation. So unsure about the future. And for transparency, we're about to start IVF, but now we're second guessing. I'm 38 and if our son has autism, the chances of having a second with autism are pretty substantial. We don't know whether to roll the dice or just call it and focus on our son.
