Where did my little baby go?

Sam looks like such a little boy in this picture, and not a baby. He's been pretty whiny lately, but he's finally starting to say more than just "car go!" (his favorite) He's started saying "doh" for window now too.

Both boys are making animal noises, such as quacking like a duck, barking like a dog, and making their mouse faces. When you ask Sam "What does the alligator say?" he clacks his teeth together and says 'gah gah gah." They are learning so much all the time!
