word up

In just about a week, Jake turns 16 months old.  Over the last few weeks, he is starting to learn to say and understand more words.  While both Shelli and myself are still "mama", he has a noise that is definately his rendition of "Kailey".  I don't know exactly how to spell what he says, but it sounds like "AAAiii - Lee".  

He is learning more sounds too.  Jake, what does a dog say?  "ruff, ruff".  Jake, what sound does a train make?  "choo-choo".  Jake, what does a monkey do?  "ooh ooh ooh eee eee [while making movements with his hands under his arm pits]".
