The title represents L's way of saying "momma." She's been doing it for a few weeks now, and while I may have put it off as random sounds, others have noticed that it's a definite sound she makes when she sees me. My parents noticed it right away when they were here last week.
I have to admit that it's cute. I need to step up using sign language with her, as it was such a help with both boys. I started with C much sooner, but around now with N. C's first sign was "all done" and N's first sign was "more," which tells quite a bit about their eating habits even today!
