Signing

Reily started to sign "milk" about 3-4 weeks ago but we weren't sure if he meant milk or he was just dancing with his hands open and closing. This week he signed "more" with his hands closed. He use to clap his hands together before with his hands open but the past 2 days we have seen him sign "more" correctly. He has also been saying baba to get attention and sounding mama but we do not know whether he knows the meanings of those words.
