Is that in the dictionary?

This is Riley Cate's Daddy, here to tell you about Riley Cate's new word. The kid is showing great potential with her vocabulary. Why would you use two words when you could just make up one new one? Riley Cate knows the words "more" and "milk" and she has been using them for some time. Now it seems that she has combined the two. Several times over the past week she has held up an empty sippy cup and said, "MOAK". It makes no sense, until you break the word down and think like a 17 month old. If you think about it, mo' + milk = moak!
