Animal Sounds

I have been trying to go ahead and teach Jackson animal sounds and to recognize the animal when he sees it.  It amazes me how fast kids learn! I was giving him a bath the other day and decided to start with the duck since I saw it in the bathtub.  I said "duck", held it up, and said "quack, quack."  I repeated it a few times and then did the same thing the next night.  He picked it up right away and said "quack, quack."  I will say duck throughout the day and he will make the "quack, quack" sound.  I love it!
