Terrible twos

A couple of days ago I finished reading Your Two-Year-Old: Terrible or Tender (no question mark -- I was tagging one on out of long experience in the supermarket aisles), a book from the Gessel Institute of Human Development by Louise Bates Ames. It's one of my two favorites among the many books I've read in preparation for Elena, which I was doing at least a year before she was born. (The other is What's Going on in There?, and that one does have a question mark in the title.)
