A.P.
I taught both of my children the basic sign language and it had helped a lot. i would buy the book Baby Sign Language Basics by Monta Z. Briant it is a small book that has 60 basic signs they are really nice when they are learning to talk but cant. My son knows, more, milk, please, thank you, eat, ect. these all have helped me communicate a lot better with him and the book was only $8.95.
