17 months and the only thing I know of her saying is purple. Maybe she talks in her sleep. But I doubt it because we share a bed. I'm doing what all of the books I've read say to do. Talking in simple sentences and announcing the names of different things to her, etc... nothing. well, I'm worried, because she should be further than this by now, I'd think. But then again, my sister didn't speak until she was almost three and at that time she spoke full sentences. Well, should I be worried? Is there something I'm missing, here?
