My daughter is 33 months old. She understands commands and is interactive with other children. She tries to talk but she doesn't talk clearly. I'm worried about her. Other children her age talk plain and ask for things. She says some words or phrases plain but a lot of things I have to ask her what she's saying and she throws a lot of fits if I don't understand. She doesn't ask for her sippi she either gets it herself or throws a fit until I ask her if that's what she wants. Should I be worried she's not talking plain and not counting or recongizing colors? Does she have a speech problem? What should I do to help her start talking?
