I am not a "SAHM" -- I work part-time from home and my husband busts his a** so that I can be here for my kids -- there is no such thing as a "SAHM" -- I am a mediator, supervisor, health care aide, and even, dare I say, a housekeeper!!
Your sister has a lot to learn about being a parent/spouse. It is a shared duty -- at this point -- my husband earns most of the money and I take care of the kids -- that's our arrangement. I am not less of a woman for doing what I do. I have a 24-hour a day job -- I'm up at night with babies and sick kids and up in the morning to take care of everyone. I would like your sister to have to pay for the hours I work
I would love for her to spend one week shadowing me -- I would doubt she could handle it
. I truly believe some kids are better off with their mom's working -- her's may just be some of them
You have my sympathy for having to stay there 25 more days -- but I have to say that was awesome of them to let you live with them (I give her a point for that!!). Just remember this comment when/if they eventually have kids -- because you will need to be an amazing aunt to make up for where she lacks!
(P.S. -- I've been married 11 years -- I don't recall any period where we fought all the time -- don't believe that is part of marriage, I'm sure you will be a better example some day!!)
I have a high level of respect for you -- even with the parents you seem to have had, you still have a positive perspective on SAHM -- thanks!! Besides, I think both jobs are difficult, yet have their rewards -- whether you stay at home with the kids or return to work.
