I think she absolutely owes you an apology that reflects her understanding that she failed you. I'm getting the sense that she understands your feelings--as they pertain to you as a client--but is she cognizant of her failing as a professional? I"m sensing that she isn't. I get that childcare can too often fall to the woman; but she's not working at a minimum wage line job. She has resources to arrange her professional life in such a way that both can be accommodated without dumping the consequences on clients. It may necessitate sacrifices in lifestyle, cutting back work hours, arranging for paid childcare, etc.


I freely admit that as a woman without children, I resent how often workplaces have expected me to pick up the slack when an employee with children says they can't fulfill a job duty. I chose not to have children and don't think I should have to be regularly responsible for those who chose to have them.


I've also noticed that parents under @ 40 yrs old can be child-focused in the extreme. In Univ circles we call them "helicopter parents" because they hover. I don't know a Univ teacher who doesn't often field calls from parents who intercede on behalf of their adult children about all sorts of routine grades, etc.


So it just wouldn't surprise me if she really doesn't see her actions as professional failings for which she owes you, at the minimum, an apology. What she really owes her clients is to manage her life in such a way that, barring true emergencies, her clients come first during work hours.
