We were lucky to have a mom with an older HG+ kid recommend a preschool teacher that her son loved. If you can find some families with HG kids and ask about any recommendations, that might be most helpful. Our DS4 is in his second year of preschool.
We felt that preschool was important because we were new in town, didn't have a big social circle yet, and really wanted DS to learn how to behave around and have respect for another adult while at the same time having a school-like experience around other kids. This is a part-time, play-based preschool (2 half days for 3-4 yo/3 days for 4-5 yo). We went to visit the spring before enrollment to get a feel for the room and saw a bunch of happy kids listening to the teacher (amazing!). I told the teacher ahead of time that DS could read, and that we weren't really interested in any academics but wanted DS to have an experience with other kids and a teacher. She "got" him right away.
We did have some problems, though. The first year, DS had never been away from mom with a stranger, and never had a babysitter except grandma. He did not want to leave mom. This took several months to shake, and then after the holidays he started some lengthy goodbye rituals. Now, a few months into the second year, we are getting longer and longer complaints of "i hate preschool," "don't sign me up again," "i'm not going to any school after preschool," and I have to drag him there every time. I am starting to think that was fabulous for 3 yo, new 4 yo is not so wonderful for 4 yo/almost 5 yo. But I can't quite figure out what the problem is, because he will only give me weird answers to why he doesn't like preschool ("it's in a church" or "the room's too small").
So, I guess i'm getting the first taste of "what might work for a little while for an HG+ kid may not work 6 months/year later."
Good luck making a decision! I'd vote for a play-based, part-time preschool though, for any kid.
