That would explain the punkitude.

I think my son is having a growth spurt, possibly his last. We compared heights last night, and I think he's only an inch shorter than I am now. I think that was more like two inches three months ago. Given that he's 18, he stands a reasonable chance of catching me. What makes this all the more impressive is that his mother is a 5'2" (155 cm) fireplug.

Yeah, this would explain all the sleeping and crankiness. As with babies, so even with teens.

It's a tremendous relief to me that those damn ADD meds haven't obviously stunted his growth. They've always wrecked his appetite & sleep when he takes them, so he only takes them when he needs to concentrate on something, e.g. school or driving.
