Moms plus merlot equals a pretty constant joke among 30-something women. At late-afternoon play dates, you'll often hear a tired mom squeal, "I need wine time to handle whine time!" Then there's that suburban myth about the preschooler who was asked to draw a picture of his family and turned in a sketch of his mother holding a piece of long stemmed crystal. And everyone knows about "moms' night out," when we let off some steam by commiserating about cooking, cleaning, laundry and endless hours of playing Barbies or Bionicles over cool glasses of chardonnay.
