"Good job, Sophie!"

Sophie is starting to memorize and repeat some of the simple scripts we use frequently in interactions with her.  Last week, she started answering questions with "bah [yes]... ok!" or "no no no... ok!"  That's because when I ask her something and she answers, I've always responded with "ok," I guess just as an acknowledgment.  This week, she has started saying "good job Sophie!" after doing something that would normally elicit that response from us.  :)  Today, when she threw a book at me and I said "no!" and looked mad, she said "gentle... baby Ben" even though he wasn't around.  I must only react that way when she's come close to hitting him.
