There is definitely this expectation. My friends who had their babies in their twenties all went back to work within 6mos. Some because they had to financially. Others because they felt it was their identity or that they wouldn’t be respected.
I do feel like there is an entirely different set of expectations once the kids are in school or out of the house. You must be productive and be available 24/7.
Even though my little is still little, “im like do you want a clean house and a raging bitch or a semi clean house and a happy loving partner?” Mamma’s got to do her things too!
