My baby is 1 year old, how to get the first meaningful word from her?

Always start with the simple words, keep repeating to her when she open her mouth, like Pa, Pa Pa, Ma, Ma Ma, when she play the ball, keep telling her, BALL. When she see dog, tell her DOG, see bird say BIRD. 1-2 words is easy for them to pick up, if ur sentence is too long, they may end up don't have the confident to say instead. When she can say 1-2 words, than you expand to 3-4 words, slowly increase the number of words.
