Mathematical motherhood -- keeping count

     The Journal of Humanistic Mathematics, with new issues coming twice a year, late in January and July, is a wonderful resource.  Their latest issue (July 2018) was themed "Mathematics and Motherhood" and is an example of their wonderful support for expanding our images of mathematicians to recognize the vital contributions of women.
     From that issue, here are opening stanzas of  a poem by Nevada scientist and mathematician Marylesa Howard -- lines that offer a mathematical description of the constant adjustments of parenthood.   Several decades ago, when I was a math professor and parent of young children, I needed to keep details of parenting away from my profession -- a divided life.  I'm glad things are different now.
