Being a SAHM is definitely harder than going out to a job, at least in my experience. I, like you, spent time at home as well as at work during their growing-up years. The hardest job of all was the family day care I ran from my home. My own two preschoolers plus three others. All by myself. That was the hardest job I ever had. My career in market research, working many 60-70 hour weeks catering to clients and flying all over the globe was a cakewalk compared to that.
