What's the deal?

I am not sure what the deal is--We are going backwards. I guess Logan sleeping through the night at 6 weeks old was just to good to be true. For some reason last night he was up at 11:00, 2:30, 4:45 and 6:00.....Growth spurt maybe? I still blame his two month shots, thats when he started waking in the night again. Good thing I have the day off today maybe I can get a good nap in this afternoon.
