"Uh-Oh"

This is a great Benjamin story:

The other day Benjamin brought me his book containing pictures of various family members. In preparation for our upcoming trip to California, I decided to try to begin to teach him to say names. We started with the grandparents.

"Can you say 'Mima'?"
"Meh-MA!"

"Can you say 'Grandpa'?"
"Pa-PA!"

"Can you say 'Papo'?"
"P-PO!"

"Can you say 'Mamacita'?"
Blank look.... "Uh-oh."
