Babies and toddlers are learning though observing adults. They can't observe there own behavior and learn though self-analysis.

I let my 14 months old daughter watch two cartoons today, one was about cat and mice (Russian cartoon "Kot Leopold") and the other one was about a monkey mother and her babies. I can definitely see myself in the character of the monkey mother and my baby in the characters of the baby-monkeys. http://www.youtube.com/watch?v=rd1dQXhgNEk&feature=related
The interesting thing is that my little one was not interested in the second cartoon at all.
