My little MM is about 13 months old now, and he has begun to say a few words. I think "water" was the first one, followed by "Mama," "Papa," "diaper," and his big brothers' names. Last Sunday I was amusing him in a small room without toys. I put him on my lap and played "This is the way the ladies ride" a few times. When we were done with that, he started climbing onto my lap, saying three words, toppling off (fully trusting I'd catch him, of course!), and giggling uncontrollably. He did it a few times before I realized that what he was saying was "Mark! Set! Go!"
The things he learns from his big brothers!
