my 2-year old is too talkative

Good for you my friend, but to a certain extent you should also guide your daughter with everything thats shes doing. Explain to her the kinds of stuff that shes telling you. If not properly taught, you might not be able to teach her alot of important values such as how to listen and how to talk properly when needed too. Its a good sign that she loves talking but then again guidance is really needed specially at her age ;)

I love the fact that my 23 month old son is talking in full sentences. Most kids that age are just learning a few words or putting 2 words together. My advice would be that you find joy in it. Be proud your daughter is talking so much and so well for her age. Maybe she does want attention from you. Maybe she wants to tell you about her day. I would try to see the good in it and try not to get annoyed.

It's completely normal behavior. I'm not buying completely into the attention seeking experts claim. Sure, it can be, but let's look at it from a different angle. As a 1 year old, they really couldn't talk. They were just learning and learning a bunch of new words. They babbled them. They played with words, made up words and just their speech in general. As two year olds, they have a pretty good handle on speech and they love the new skill that they've learned. They enjoy knowing that they can talk to Mommy and daddy and everyone else and that for once, they can respond because they are understood! It's a wonderful feeling. In my opinion, the talking is probably more of a skill issue with bouts of random babbles for attention. For the most part, the best thing to do is remind your child to use their words, talk like a big girl, etc. Reward the good, ignore the bad. It will sink in eventually that you're more interested in her real speech instead of all the randomness.
