I am sure my husband will think I am out of my mind if I tell him I am thinking about sitting in on the kindergarden class!
You don't have to share that particular moment with DH, he'll get there eventually. Start with DH by asking what his elementary school experiences were like, and when he learned to read. Ask if he got subject accelerated or was offered a skip, or knew anyone who skipped. Ask if there are any family relatives who quit school because it just wasn't relavant. Start asking your relatives the same kinds of questions. I have a sibling and a cousin who taught themselves to read at age 3. My son, who is 'profoundly gifted' by Davidson's standards didn't learn until 1st grade. Part of the reason that your child looks somewhat normal may be that your family is all or mostly gifted to start with.
You aren't looking for kindergarden classes for your child, you are trying to get a feel for what is 'normal.' Teachers aren't evil when they don't meet the needs of highly and profoundly gifted kids, they are just used to doing what works 99% of the time.
As for skipping K - or pre K - there are pros and cons. If your child is happy and not getting the message that adults are really really stupid (else why would they get so excited about the letter K? else why would they be so suprised and excited that he is reading?) then it's fine to let him go. But I would also make sure that you are laying the foundation for 'learning to learn' by having at least 5 mintues a weekday devoted to some learning activity that is actually challenging.
If the K program is a half day, and not 'academic' then lots of kids enjoy it. OTOH, lots of 'advanced' kids are deeply offended by the normal curricula. Personality makes a big difference.
