The actress, who stars in the forthcoming film I Don't Know How She Does It, revealed that she feels lucky to have a job that she enjoys, People reports.
"I know that there are women that are working not because they want to, but because they have to - and sometimes more than one job," Parker said on This Morning.
She continued: "And I'm far more in awe of how they manage to do it all than [of] myself, because I think I have the liberty to pick and choose when I can work, and I have the kind of support I need."
The mother of three went on to credit her children with keeping her in shape.
"My daughters insist on being carried at the exact same time," Parker said. "They're like 25 pounds now each."
In August, Parker insisted that she and her husband Matthew Broderick do not have a live-in nanny since they prefer to be hands-on parents.
The actress recently revealed that she is unsure if there will be another Sex and the City film, saying that the timing is not quite right at the moment.
