normal?

This morning as I was frantically trying to feed James, clean the kitchen, and pack a gym bag...I looked over and saw Thatcher laughing and smiling while throwing cheerios all over the floor. He had apparently been at this for quite some time because there were cheerios everywhere. I could tell he was having fun and not trying to be naughty so I explained to him that we shouldn't put food on the floor and to please pick up all the cheerios. He started right then and even though it took him a while, every last cheerio made it back into the snack cup. Is it normal for a 2-year-old to be so obedient? How did I end up with the sweetest, happiest, funniest, greatest toddler in the world?
