It has been reported that Terri taught Kyron sign language when he was a baby. I did this myself with my children so that I could better communicate with them until they started talking. They started signing at ~5 months old through when they fully started talking. Since all my DS knew sign, they all signed with each other until the younger ones could talk. Here's a basic link on the common baby signs: http://www.babies-and-sign-language.com/glossary-photos.html So, do you think Terri also taught Baby K to sign and if so, what would Baby K be able to say via sign about the day Kyron went missing?
