It's 2am and I Feel Like the Living Dead

It's 2am and Ash and I are watching a Geotrax train movie. We got about 30 minutes of sleep early this evening but that was it. How can I already be exhausted and we've only been in the hospital 28 hours?

Ash is scheduled for the first surgery in the morning so I expect them to take us down to the OR around 7am. Please keep praying. Ash isn't the toughest little guy in the world and he's already beginning to dislike this hospital.
