Ms. Little Fingers loves the Stop GO song from Baby Signing Time. GO is one of the core words that help with language development. When I say that I mean that GO is used for so many things, not just 'doll' and it only means the plush baby toy a child plays with. ... rather, GO means "Ready set GO" during a race or game. Cars GO. You ask someone to GO if you are waiting for them to move ... there are many reasons to use GO.
