forever changing into a little girl

Where in the world did my baby go? I realized I was hearing her call me "mom" instead of "mommy" for a few days and her sentances are becoming more accurate and less "cute" as we have called it. Instead of "whad you do?" she says "what did you do?" But at the same time, it sure is easier to understand her!
Although, we have had a few backslides...in the sleep department, of course. She is overwhelmed every night in the dark room, even with her new turtle nightlight. Most nights, she sleeps in the big bed with mommy, which she now calls "kira's bed." Uh-huh, ok. I don't think so!
