My son is at the age when he takes his obsession with one small thing and makes it big. He has learned to generalize. When his obsession was dinosaurs two years ago, we took him to visit the natural history museum. It was a big day. Father and son, palms leaving prints against the train window as we crossed over the bridge. My husband believed you could tell how good a day it was going to be based on how sparkly the water was. There was a definite shine then. My daughter was asleep on my lap, a weighted blanket.
