It took me almost a year to calculate that my kids, Sylvia and Nico, were 15 months apart. When Nico was a newborn, people regularly commented on my "full hands" and asked me how close the kids were in age. My response was well-rehearsed but vague: "She's just about a year older than him." I was too sleep-deprived to do the math.
