Each of the kittens is showing more personality every day. Kara (the one in the front of the picture) is definately the heavy-weight of the group. She can usually be found pushing her way into the center of the pile, or pushing her sibs out of the way of the food she wants.
Tag seems to be fairly adventurous. The other day, Dee stepped out of the cat carrier and flopped down beside it on the floor, clearly tired of being nursed on. Within 60 seconds, Tag had crawled out of the cat carrier and was latched on nursing again.
