Thank you both for your responses!
What is confusing is that he is generally well behaved at home. He has his moments, for sure, but is is SO MUCH better at home then it sounds like he is at school.
We are trying to remain open minded about where all of this might lead up - whether some sort of therapy or even medication. But we really have a hard time accepting the idea of medicating a 3-year-old. It's good advice to exhaust all other avenues first, irishmaggie!
I'm so glad to hear that both of your kiddos are doing better now. I think a lot of this is just part of his personality and who he is. Giftedness may or may not have much to do with it. I don't know... we haven't been able to put our finger on what, exactly, is going on yet.
I hope this psychologist we are seeing next week will be able to offer some guidance.
