Babies are work. They are constant, screaming, pooping, work. Not even 9-5 work, because a very young infant requires around-the-clock care, so really it’s worse than work.
At least in a regular job you can punch out and leave work at the office and go home and relax, or call in sick if you don’t feel good. None of that with a baby. You have to always be there for them, all day, all night, no matter what, no matter how you feel.
I think we’re also running into an issue of language, however. ‘Time Off’, as in, not being in the office for an extended period of time, yes, maternity leave is that. ‘Time Off’ as in, a rest, relaxation, vacation, no. Maternity leave is most definitely not that.
