Walter has words! Many words. And many of those many words sound incredibly a lot alike – they sound like "Mama." Mama is Mama, of course. But then Molly is Mama; Grandma is Mama; Elmo is Mama; both Emma and Ginny (Walter's cousins) are Mama. You need a sharp ear and some visual clues to tell you who he's referring to. I don't mind sharing my name with so many others. In fact, I'm pretty darn happy it's one of his best spoken words. Of course, there's only one "Dada."
