I hate to see so much disagreement and hard feelings between members of the same faith. Just so you know my wife and I have been married 7 years, and have two boys(5 and 3). Motherhood is not something that comes naturally to my wife, it is a daily struggle. She struggles with patience, anxiety, depression, and lack of self worth. Many days, she wants to take my boys to a daycare, and get a job to help with bills. It has caused some struggles, and hence we are waiting to try for another, because WE don't feel it's the right time. Maybe we won't have anymore, we have to pray and try our best to gauge when we will be able to provide a stable and nourishing environment for another child.
My wife is very intelligent, and has excelled at every job she has ever worked. She had two years of college under her belt, and a good job when she became pregnant with our first, (5 1/2 months into our marriage, boy were we not prepared!) My wife hears all of the time about how her friends have their degree's and great jobs. She feels like the world looks down on her for being "just a mother". On the same side she feels pressure from the "Molly Mormons" about when are you having another child, is your home spotless, have you read the entire Ensign this month, ect. Man, I am glad I am not a woman!.
I guess what I really want to say is that like many things in the Church, each individual knows when they are doing their best. We can receive personal revelation for ourselves and our families. It is definitely not one size fits all, and even though some are intrepeting Sister Beck's talk that way, I don't that is the message she meant for every individual. Only you and the Lord know if you are doing your best, or are capable of having a family, ect. My wife and I were not offended nor did we disagree with Sister Beck's talk, my wife would love to be "Super Mormon Wife" with lots of perfect children, spotless house, delicious 5 course meals every night, just as I would love to be "Super Mormon Husband" have no debt, have the scriptures memorized, conducting perfect family home evenings, ect. Until then, we will keep trying.
Finally, I don't think there is anything sacred about dishes or other housework. My wife expects me to help out with the kids and housework when I am home, just like I expect her to be doing productive things while I am at work. Both companions giving 100% and not saying "That's your job, not mine". Sometimes I need a guys night out, or Church basketball, and I encourage my wife and any other wife to take some time for yourselves, or you will go insane.
