Welcome, shapeshifter! I think many of us found this forum because we too didn't have an outlet for talking about the things our children did. Your DS sounds quite GT to me. In case you haven't found these yet, here is a link to early behaviors of GT kids:

Enjoy your child, and feel free to share stories here. I for one love to hear about these amazing children!
