Reagan still has far fewer words than I would expect considering how well he understands us and how well he gets his point across. However, he has picked up his brother's favorite word, "Why?". I have tried to explain to him that most kids learn a few more words before picking up on asking "Why?" all the time, but he simply responded "Why?". ;)
My absolute favorite is when Reagan is asking "Why?" and Cooper answers "Because". I swear I try so very hard to not use that as an answer to Cooper's questions, but it must be slipping in. . .

Some of Reagan's other words:
Move (when he wants you to move)
Hide (when he wants to hide under the duvet)
I am sure I am missing a few. Of course, as a second child, I am not keeping as much track. . . oops!
