stay at home mom

Do you think that being a stay at home mom is really a hard job? I don't have any experience with it, so I can't really say. But I feel like most women take care of the house and the kids along with having a job. So I just don't see how it could be harder if you only do half of that? But again, I don't know, I haven't had any experience with that. Not trying to bash on any women who are SAHM or any women that are not, that's just how I've always felt about it. What do you all think?
