My older son now 5, incessantly talks. Usually wanted feedback, but sometimes not. From 2.5-3, he would recite books all day long. We had to enforce engaged communication at the dinner table. As others have said, by 3.5-4, he was reading well and that helped. He still talks and questions a lot, but the burden is somewhat shared between myself, dh, and ds2.

Hang in there! Yes, it is exhausting. Yet, I truly believe I am happy that my 2 crazy boys are much, much more interesting and fun than those quiet, obedient bump on a log kids.
