B.C. (before children), birthdays are an occasion to celebrate. While they always remain so, many women are less inclined to make a big to do about the date once they have children. It's not that moms are less important or undeserving, it's often that they look forward to planning and celebrating their baby's birthday more. Not only did I forget it was my birthday last year, I forgot how old I was. Many mothers agree that the best day of their life came when they gave birth so it's no surprise that they identify with that date. Besides, most every mum I know would choose sleeping in over cake anyway.
