We've been working with Charlie for months to get him to start calling me "mommy" again. He used to always call me "Mommy" or "Mama" until he learned to say my name, and he started calling me "Kim" instead. Very sweet, and I'm glad he knows my name, but I much more desire--or perhaps need--to hear him call me "Mommy".
Well, We have much improvement lately. He IS calling me "Mommy" more often, though not most often just yet. And, instead of "Kim" he is now addressing me as "Kim-ma", which is a combo of "Kim" and "Mama". Hey, it works for me.
