There are so many things wrong with this post, I can't even begin to list them. All I can say is, if you're trying to talk your friend into having a baby, Janine, this is definitely NOT the way to go about it. :p (Not that anyone can, or should try to "talk" someone into having a baby they're not ready for or not sure they want, anyway...).
A few responses I've run across (hearteningly, many of them are written by mothers):
An Open Letter to Janine Kovac (also on Role/Reboot)
Open Letter to 'Clock-Ticking' Childless Women Makes Moms Look Condescending & Self-Righteous (from The Stir)
Motherhood isn't the path to enlightenment for all women (by Mary Elizabeth Williams on Salon -- the first piece I actually read on this subject). How can you not love this summation at the end:
Take it from a mom, Doris. A very happy one whose daughters are straight up the greatest people in the world. Have kids. Or don’t have kids. But you don’t have to make your choices based on the incredibly condescending notion that raising children is the way to enlightenment, or that the alternate road leads to having nothing in life to care about but your iPhone. The only person who can ever fulfill you is you, Doris. And you have infinite worth and value right now, just as you are. Don’t let anybody ever try to tell you otherwise.
