It's 4 am..where's your baby?

So, Margot now thinks it's funny to wake up at 4 am, cry until you come to the nursery, and then look at you like "I'm not tired...this is fun!" Then she smiles at you, and you are powerless against her. She will go back to sleep fairly soon, but what happened to little miss sleeps all night? We love you Margot, but could do without the 4am interlude. Just a thought.
