L.S.
I just read through almost 200 applications for one job we are hiring for. Do not use the term "domestic" anything. If anything, use a phrase like "family responsibilities" and do not elaborate too much at all. It may not seem fair, but the truth is that when you mention that you left a job to become a domestic engineer, employers may question your 100% commitment to working now. I know it isn't fair, but that is how it is.
In this economy it seems like there are a lot of non-traditional resumes because some folks are returning to work after retirement due to the crash and spouses who never thought they would have to work and now trying to find work because their partners have been laid-off. I saw quite a few resumes from folks with very powerful degrees who are working at restaurants and Starbucks while they are trying to survive. I am mentioning this so that you will see that having a gap is not that unusually now...and anyone reviewing your resume will be able to figure out that you probably have been a stay at home parents during the "gap" without your elaborating.
