Your daughter sounds like she is right on track. I thought I'd let you know some information that my pediatrician gave me- as my three kids developed very differntly from one another. Language development (and cognitive development, in general) often slows when the child is at a significant physical milestone. So, when a child is learning to walk and run, you may notice that language development slows while their brain concentrates on the physical.
Also, as her language skills develop, you may find your daughter may be very frustrated, at times. She will know what she wants, but not know how to say it. This often results in behaviors like hitting the pantry door and screaming when she wants a cracker or banging on the fridge when she wants some juice. My pediatrician suggested calmly requiring that the child "use their words" in these situations. Otherwise, they will very quickly learn that banging and crying gets them what they want.
Finally, remember that every child develops at a different pace. There are averages, but there are very large variations from the average that are normal. My first child was talking a blue streak with long complicated sentences by 20 months. But, my second child was over two before we could get her to use phrases and sentences. I was very worried - but she is now a perfectly normal 9 year old. They just had different developmental patterns. (The second one was VERY physical! She had no time to "waste" learning how to talk!)
Enjoy this stage!! You finally get to know what they are thinking. It is a wonderful time to be a mom.
