I've been bad at updating Jake's words on here (oops!) but here are some new ones over the past few weeks:
Penguin (only he says "Mengui" if that counts as a word) :-)
Water ("WaWa", not to be confused with the Eastern PA convenience store)
Amy (pronounced "Mamee")
Elephant (complete with hand motion for trunk)
And here he is modeling his "What do YOU want?" face.
