It almost hurts to listen to your story because I remember how scared I was when my son was 16 months old. Talking and obsessed with the alphabet. One time when he was 16 months old, we were at the store and my husband saw someone he knew. She walked up and he said, "Mommy same shoes" and I looked down and I did have a pair of those shoes. I wanted to just be shocked and squeeze my husband to say, "Did you hear that?!" but I just continued with the conversation.
If I could go back in time, I would tell myself: keep a journal, hang on tight, find atleast one human friend to talk to about this, frequent these forums, and let him go to the places he wants to go, whether it's Elmo or geography.
The parents on here have given me so much support.
People will always think you "made" him that way, forever. Our DS is now almost 4 and I am finally not allowing those judgements to bother me.
I know exactly what you mean by recalculating having more children. We chose and were fortunate to have our boys 25 months apart and I wouldn't change it for anything. Our almost 2 year old is obsessed with clocks and shapes and it makes me wonder. I have no idea if knowing shapes is normal at this age. I still don't have a feel for what typical milestones are.
