Strong Willed......Where could that have come from?

Okay, so since Sadie turned one, she has started this thing at home. It is called "I don't need an afternoon nap". She only does it at our house and it's pretty weird. She goes into her crib and never takes a nap. She seriously lays in there for two hours talking and eating her toes and then after two hours sometimes she finally falls asleep. In the picture below, I guess she just got tired of herself and gave up. She must have definitely got her strong will from mom and dad!
