Do you have time to talk to your daughter every day? My son has 16 months, he can only say few simple words like - up, mam mam, papa, ball ball, nai nai, kung kung ...
Suggest you talk more with her, read a colorful book with picture and watch DVD (for their age). They will learn it quickly. My son knows up and down, turn around, open and close, jump, step the feet, clap hands ... via DVD.
