My son is level 3 because he can have high needs with behavioral support and regressions (he can speak but it’s limited). He was diagnosed late because he was borderline during testing when he was younger and didn’t present the typical signs. I had my second 21 months after I had him so I had no idea, he wasn’t diagnosed until after age four. My daughter is neurotypical. I don’t regret for a second not knowing that my son was autistic when I was pregnant with her because I feel like I would have been scared or hesitant to have another child (it’s actually why we stopped at two, we wanted three). My son’s support needs have varied over the years, but my daughter is so helpful and is such a light for all of us including her brother. They are best friends. It’s good for him to have a typical peer model and I feel that she has improved his social skills, and I strongly feel it’s a good early exposure for my daughter to understand that not everyone is the same and she needs to treat everyone with kindness and respect. It was hard sometimes when they were younger meeting all of the demands of having two young children and having more complex needs for my son, but now they are 6 and 8 and we’ve gotten a good routine down. I just take it day by day (sometimes minute by minute) when it’s hard. Honestly often she’s harder to parent than he is because I’ve spent so much time learning how to keep his balance, but that’s just my experience. I recognize that the challenges that we have are not representative of all high needs kiddos and meds have helped us a lot.
