I am actually a little worried about DD. She was saying Mama for me and me only since 7.5 months, but now she barely says it.
As long as it hasn't disappeared all together and she is still developing normally and not regressing, then I would not worry about it. Is she adding vocabulary on top of what she already knows?
Unfortunately I do have one of those kids who lost all of their words by 15 months and the change in him was incredibly drastic (can't stress that enough!).
If it really is weighing on you, don't be afraid to ask your pediatrician if they think an early intervention evaluation is necessary. From what you mentioned, she sounds fine but I just wanted you to know that option is there!
