How could I forget?!

Emma is trying to talk. she was saying 'ba ba" the other day, so i tried teaching her "ma ma". She loves to say "ma ma' now, but she has no idea what it means. She calls all of her toys ma ma. Now, when she's upset or angry, she yells out "MA MA". I figure if I keep acknowledging her when she says it, she'll figure out ma ma is not an all purpose word. She has also amended it recently to "mom mom" She is a silly one! I love to hear her trying to say words now!
