I have also never felt guilty about working. My kids benefit so much from me being engaged and fulfilled, not to mention they wouldn’t be going to their lovely private school without my salary added to the family coffers. My children live in a family without gender roles (mostly) because they have two homes and two co-parents who cook, clean, arrange doctors appointments, go to birthday parties, etc. They don’t think, “Daddies do this. Mommies do that.” Grown ups work. Grown ups take care of the house and kids.
Sure life is much different with children. It grows and contracts as families grow and needs change. We sacrifice a lot of freedom when we decide to be mothers, but I feel like the rewards and unexpected lessons are well worth whatever I might be giving up or missing out on.
