A couple of weeks ago, flipping through the Boston Globe business section, I came across an item about a $200 clip-on baby monitor that shook if your infant didn’t move for 15 seconds. Wow, I thought. A guarantee that your child won’t sleep through the night. And another unnecessary baby item to join the video monitors (because clearly you want to watch the kid crying, too) and the rubber ducks that light up with the word “HOT” on the bottom if your bathwater is too warm. And then I thought about Jesse’s obsession with lint, and how much more he likes trash than most of his toys. And presto, I had a column idea.
