Hi J.,
I'm not sure how much your daughter is talking, but at this age she should be able to ask for what she wants. She should also be starting with 2 word phrases such as "Mommy go". Many times at this age you'll start seeing frustration because they can't get their idea across.
There are 2 types of communication. One is receptive, her ablity to understand what is being said or asked of her, such as simple commands. "Go get your shoes" Where's your nose?" (sounds like she's doing OK with this). The other is expressive, her ability to verbally tell you what she wants.
I suggest you contact your local Health Department. It maybe City or County depending on where you live. Ask to talk to someone from the Help Me Grow Program. They work with kids from birth to 3 years. Early Intervention is part of the HMG.
They will do a visit and probably an evaluation to determine if there is a problem. If there is then they will give you some options that are available to you. This is all free to you. It can be very helpful, and may help her get on track if she's not doing what she should. All HD do things a little different, but the basic idea is the same. It is to help kids. It would be up to you to decide what services to use if she is eligible.
How do I know? I work in Wood County's program. Please feel free to write if you have questions.
Good luck to you and your daughter.
