Do you know why this baby is so happy?

Matthew slept for 8 hours straight last night and he's taken 2 wonderful naps today...one 2 1/2 hour nap and one 2 hour nap. You know I like schedules and this baby definitely needs to get on some sort of sleep routine. I hope we have more days like today. He is always a very happy baby but today he didn't even fuss when he was tired. If only I could say the same for Tyler today. After a day full of playing with Jeb at the zoo, Tyler did not take a nap. He actually laid in his bed for 2 hours and did not go to sleep. Someone is going to bed early tonight! And hopefully Matthew will sleep all night again. My fingers are crossed!
