Yes...........TALKING...............he's got a memory like an elephant, a mind as quick as a trap door. Just yesterday he asked about how we get day and night, and he asked about aliens, which led Big Son to ask if ancient Romans had technology, and Little Son said they had gladiators who fought lions...............and then he started talking about if it's better to be "fired up to ashes" or "bury your bones" when you're dead...............I have no idea where he gets all his ideas.
Today, he was sitting on the toilet singing, "We are family.........."
