Camden's words and sign language

We have been teaching Camden sign language, and he is getting so good at it. He currently knows about 25 signs and I have to pay close attention to him so I can see when he is telling me something. He also knows about 21 words (some of them are the same as his signs). I looked up on a child development website, and an average 15 month old usually knows about 14 words, so I guess he is pretty average for his age. Good job Camden!
