What is sleep?

Around 2am Vaughn started fussing. After both of us getting up to put his pacifier in his mouth several times, I finally brought him to bed with me. Then Gavin and Lincoln started in. I finally quit fighting Vaughn around 4am when I got up to feed him and pump. It took him about an hour to get back to sleep. The other two boys were up off and on until the 6am feeding. So basically Jamie and I have been up since 2. But I still had enough energy to go garage saling :)
