Diagnosis Unknown

Someone, and I'm not naming names, has been quite the crabby boy lately. Maybe his one-nap schedule is catching up with him, maybe it's his teeth, or maybe the planets are misaligned...I don't know exactly what the deal is, but he has been waking up way too early and then acting like he'd rather be sleeping once I finally go get him out of bed. He's had bad mood swings and has been especially clingy...Grrr, I wish I knew what was wrong. For now, I am just trying to give him extra attention and appreciate his upswings, while praying he'll pull out of this funk soon.
