Women in the workplace often hit a stumbling block when they get pregnant. There's an assumption they can no longer handle the work or somehow have less drive. And I believe that's why these two inspiring images of women at the top of their game looking powerfully pregnant, struck such a chord this week. Serena Williams who won the Australian Open while 7 weeks pregnant is featured on the cover of Vanity Fair while Alysia Montano is photographed running the 800m in the US Track and Field Championships also 5 months pregnant. Both look invincible. That's not to say every mother can do this or feels like this way during pregnancy. I suffered from terrible morning sickness and could barely walk fast let alone run when I was pregnant, but my drive and ambition remained unchanged and if anything, increased once I had the baby. I hope these images serve as a reminder to all that having children isn't an impediment to career success.
