Where is that damn rule book?

Ok, I feel like an idiot. I spent almost 2 hours trying to get Katie to go to bed and stay there until I realized she might be hungry. She's only been nibbling and sipping all day--I guess because she's not feeling well. So she sucked down a few ounces and literally fell out within a few seconds. Dead asleep in my arms. Poor thing. You'd think after a year I'd know what my child needs. D'oh!
