How can I teach my little girl not to be a screamer ?

My 13 months old daughter is getting use to scream every time she wants something,which it was ok until she started doing it to get ANYTHING she wants,she doesn't speak many word just makes a lot of sounds,momo,dada,papy and dog.How you moms do it.I 'd like her to try to communicate better,and please stop screaming for everything.......

    My two year old screams when she is mad at her brother. I'm trying to teach her to use words and talk.. Or show me what's wrong, what she needs.
    Hm. interesting.
