Say "Mama"

Kaia has gotten to the babbling stage. She says a few monosyllable words over and over, one of which is mamamama. I know that most of the time she's just babbling and not really meaning to say "mama". But she does understand that I am "mama" and Josh is "dadda". If I'm holding her and ask her where Daddy is, she'll look right at Josh and vice versa. Today I had a personal day and Kaia got to spend the afternoon with Josh. When I got home she looked right at me and with a huge smile said "mamamama"! I think she was really meaning to call me mama! It was very exciting!
