Can't she get someone to watch him?

So, as you all know by now, my son is 2 years old. He was sick last week with a stomach virus. Anyone who has kids knows that when a baby is sick, they just want mommy(or daddy, sorry guys). At 2 years old, there's also slim chance they can communicate what's wrong. Enter mommy guilt again. It's not bad enough I had to feel guilty leaving work early to pick him up when I got the call from daycare and take off the following day and then morning after that; but to come back to work and hear that the question arose... "Can't she get someone to watch him?" My child is sick, who is anyone I work with to question who takes care of my sick baby? And you can rest assure it will be ME!!! Did I mention I always make up my time by working at 11:00 p.m. when these same people are either sleeping or out partying? I produce twice as much as any non-parent out there, yet the second I must step foot outside the office for my son, my work is questioned. In all fairness, I must say, it was not my manager who rose these questions, it was in fact women in the office. It amazes me how women fought so hard for equal rights and it is women who degrade mothers the most for wanting to also take care of our kids. Seams to me there is something wrong somewhere. Is it really possible to have a thriving career and a happy family?
