Isaiah is a really friendly Little Man, which has pretty much always been the case with people. He LOVES people, and usually people seem to love him, too; I think he expects such a response. Recently he's started to get attached to a few other things, too.
The other day he suddenly didn't want to be separated from Baby Tad. Baby Tad went everywhere with him--riding the motorcycle, eating lunch, diaper change, the works. And since that day, Isaiah gets really excited every morning when he sees his little friend.
