Query: 35 Signs at 11 months

My son is 11 months old. We started signing with him at 8 months. We started using the first signs video at that time. He picked it up right away. We recently got the Sharing Signs DVD. He immediately started trying to do these new signs. It was amazing how fast he picked it up. Not only does he know the signs while watching the video, he uses them each and every day. We will walk outside, and he will sign tree. We are in the grocery store and he signs apple. We were in a toy store, and he saw a giraffe... He immediately signed giraffe. It is absolutely amazing how much he is able to communicate with us before he is even a year old! These videos are a wonderful tool!
