David is now 16 months and he can...

Say "Peeeaasseee" and sign please.
Say "Moooaaa" and sign more.
Say "Ba Ba" and sign for bottle.
Say "Baaoooo" for book.
Say "reeeeeeeaaa" for ready.
Say "Up."
Say "Hup" for help.
Sign food.
Say "No"
Shake his head no.
Wave his hands "no way."
Hold an iphone to watch youtube videos on it.
He can point to his head.
He can point to his nose.
He can point to his belly.
He can point to his belly button.

 I am obsessed with him.
