My 3.5 year old is like this too. We have a ton of discovery channel
Stuff on dinosaurs on Netflix that we watch together, we have a library of science books for kids that we read whenever she has a question. We also have a museum membership so we can go experiment and play.
I'm one of those never stop, always needing to be doing 50 things types, so I don't mind it as much, but it makes my introverted husband nuts! We have instituted a "think first" system - where before she asks a question she has to think about it & present an answer first. A lot of times her questions are too complex for that, but it does cut the other chatter.
So we get well worded and thoughtful questions with a somewhat reasoned answer as a response. It also helps us to gague her understanding of what she's asking and also to address any misconceptions she may have "resoned"
On the way there!
I am looking forward to her finally putting the pieces together to reading more than a few words so she can read some of these books herself and maybe get even better questions!
