I am so impressed with this book. The people in it are so diverse which is awesome and it's pretty easy to learn the signs myself before I teach them to my one year old. He loves the pictures and he's picked up quite a few signs pretty quickly. Baby sign has made it so much easier to communicate with him, he's not talking a whole lot yet, mostly babbling, and while I usually understand what he's saying just because I'm his mom, other people don't always know what his "words" mean. I taught some basic signs to his grandparents so they could understand him and he's much less frustrated now because he can communicate what he wants. I plan to use this for all of my kids in the future!
