How many words?

I was starting to worry about Archer and his word level being too low. But just in the past few weeks his language skills have exploded.

Here are the real words he's using:
-Mama
-Daddy
-Gigi
-Perpaw
-Papa
-Ami (My sister's name is Kami)
-Baby
-Hi
-Hey
-Bye
-BeBe (While pointing to his belly button)
-Whassat
-Wanit
-Poopy (When asked if he's poopy he says it, but doesn't tell us)
-No
-Numnum (For food)
-Cookie
-Cracker

Psuedo Words
-GooGoo (For something to eat or drink, it's multi purpose.)
