I worry about my kids too, because I have bipolar, my biological mother had some serious psychiatric issues going on and my father had some too.

But I have to take it one day at a time and put my mind at ease by telling myself that there is no way that I would know right now. But the thought of genetic inheritance still lingers in my head every now and again.

My daughter was a mute until she was 3. She also went for intensive speech therapy. She's 11 now - no problems at school and has infact done really well this last semester.

It's good that your son has the option of going mainstream with additional support. That's great for him.

I'm sorry to hear that you think you may have made mistakes on your son who is 16. The hardest thing about parenting is that it just doesn't come with a manual. We do what we know how to do best at the time. Don't be so hard on yourself. This whole parenting thing isn't that easy when we have children that are all so unique and what one parent will do with their child that works just doesn't work with ours. I don't know what issues your 16 year old went through, but it certainly sounds to me like you're doing everything possible to help your 4 year old. Hats off to you.
