Autoimmune Connections

I have a question about type 1 diabetes in a child. I've listened to almost every podcast, and you often say the body doesn't make mistakes and talk about other autoimmune diseases, but I haven't heard much about type 1. I might be crazy to think it could be reversed, but I can't help but think back to my kiddo's first few years of life. He was put on PPIs and had a surgery around 9 months that involved large amounts of antibiotics. He was diagnosed with type 1 diabetes when he was 3, and he is now 6. What are your thoughts around type 1 diabetes and whether it can be reversed? Where would I start? Nothing I find on the internet gives me hope, but I believe in our bodies' ability to heal.
