Sue Shellenbarger, who writes the Work & Family column for the Wall Street Journal reports on new Bureau of Labor Statistics data showing more women staying home to be with their young children. She reports that about-to-be-released data shows that women from all income groups are tending to stay out of the workforce, usually for one to three years. The column notes the case of a mother and father who are teachers in Overland Park, Kansas, and who say that their knowledge about how babies' brains grow was a major factor in the mothers' decision to stop working after their twins, now 2½, and their third child, now 15 months old, were born. At home, Ms. Gunderson says, "I try to make sure everything we do together involves some kind of learning."
