Sex and the City star Kim Cattrall does not like the word "childfree," and neither do we."It sounds like you're less because you haven't had a child," she has said . "There is a way to become a mother in this day and age that doesn't include your name on the child's birth certificate." With Mother's Day here again, we may be focusing our gratitude on moms in the traditional sense, and that's lovely. But what's also worth celebrating is the love, care, mentorship, guidance, and inspiration that other women bring to our lives.This isn't to say that everyone who identifies as female must be "nurturing," regardless of whether or not she has kids of her own, or that emulating the qualities typically associated with motherhood makes anyone more of a "woman" than anyone else.
