Yesterday I was "testing" our ten month-old baby Kenny.
I started out by asking him, "How big are you?" (He showed us.) Then I sang "Pat-a-cake," and he clapped along.
Then I said, "What does the cow say?"
Kenny said, "Mmmmmmm."
Then I said, "What does the sheep say?"
Baby answered, "Baa!"
I thought that was really cool. Besides "Mama," and "Dada," and "Duh" (for bird), baby says "Mmmm" and "Baa."
I am looking forward to communicating more with the baby. It is really fun.
