She is totally fine! For her to say dada and mama at this point is great. I know older babies who can only say that at this point. They should really start to vocalize more around 15 months and up, not to worry. You are reading and talking to her, that is what she needs. Try to limit the television, a few shows are fine to watch. My son really started to use his words around 18 months. The binky won't limit her speech either unless its in her mouth 24/7 and she has no opportunity. My son had his for nap and bedtime until 23 months. I say cut it off by 18-24 if not sooner just because they grow so attached to having it. You are doing fine, not to worry!
