Cute!! She'll have mama down in no time :))
Iris says and yells mama when she's upset, lol, and looks at me as she says it if I'm in the room. I think that's the only "word" she intentionally says. She bables dadada and bababa a bit, and occasionally she has 'sentences' where every 'word' is different, but of course completely nonsensical.
Lexi says Dada and Baba. She'll say Dada when DH is at work, but she always yells it and looks around. When he's home, she'll say it and try to get his attention. But, Dada was her first actual "word."
Very cute. Although they can string together consonants now, they don't understand the meaning of words yet. Zoe will often babble "mamamamama" and the other day she said "buh bye" when DH left for work. But she has no idea that these are actual words or spoken in the correct context.
Keep practicing, though!
