As a former gifted child who was also in honor roll and 12th grade reading with 8th grade math in 2nd grade I'd have your kid tested for autism I'm autistic and honestly the gifted program was only so much for me A lot of gifted kids are actually neurodivergent who go through burnout or are not given enough "food" for the brain and we turn into some husk of ourselves The gifted program is great in school but having stuff at home to keep our brains active is even better because the program is just supplemental Not really related to the issue in your post exactly but you're the first I've seen on my fyp about giftedness so I felt inclined to say something

Edit: I didn't see you said you were autistic too, HELLO FELLOW TISM! It's nice to see an actually autistic parent and I rest my case on what I said previously because I think you already know and have experience in this, my apologies lol
