Are there any high profile career that are? Hell, even normal jobs for that matter. I can't imagine why there should be exceptions for more than well paid politicians with stellar career.
I can't imagine hiring a lawyer taking care of kids while working for him, even if he's not doing it on my time. Or my coworkers who can leave work every day for child concerns.
I'm sorry your coworkers get privileges you don't, but yeah, why should mothers (well, parents, but mothers typically still do the bulk of parenting in the early years) be excluded from being part of the group of people who represent your country and make decisions on its behalf? I'm personally, a big fan.

Taking care of children is a full time job. It is not one that can't be accomplished by three part-timers, and I know many successful two-income families who split the responsibility between two parents and a grandparent or nanny.
Taking time off to take care of your kids is an absolute necessity. Being a primary caregiver and holding down a full time job is absolutely untenable.
