One sign Huck is working on is "light" and we use it for overhead lighting as well as flash lights. He is amazed that he can shake the flashlight and the light is under his control. It is quite funny. We had lofty plans for this weekend, but the rain foiled them. So, we shall go to the zoo another time! He is walking all around these days and seems quite proud and his expression is priceless. I love that little guy!
