Zoey saying "Mama"??

Well, had a great time in Decatur...showing baby Zoey off to all our friends.  She's been jabbering a bit more.  Seems as if she's saying "mama" (but usually that was right before she was getting upset/frustrated).  But it's becoming more common now.  Even the daycare says she is saying "mama."  Not sure if she knows she saying it though. :-)  Now we gotta work on "dada" and "izzy"  :-)
