Start communicating with your baby. Baby sign language! The Martin family does this and it cuts down on sooo much frustration for Joco, as he can tell us what he wants, instead of just grunts or crying :)
A fantastic sign language website! Click on the blue link "Take me to the ASL Browser." Click on a word on the right side of the page and a video pops up to show you how to do the sign. I use this all the time and recommend it to my families to use at home to help their little ones communicate.
