^ Wow, bitter much? Generalizations and nothing but negativity is an outstanding way to look at this. Sounds like you're not speaking from experience.
Edit, took too long to reply. Geekbabe was last reply when I hit respond.
To OP, who cares if it's not a popular opinion, or if some feminist look down on your wife or situation. We've lost contact with a few "friends" because they don't agree with her staying home. Because how dare she not work and show the world who she is. We talked about it a lot, and it was 100% her decision. It's been 3 years last month. It's what she wanted, and I back her. It's such a relief for me working, to know she's got home life on lock. You guys should do what is best for you. Child care can be extremely expensive. Especially for multiple kids. Working for just child care seems silly to me. It can easily be 1k a week for two kids. When they start school, things can change and be easier financially.
My wife stays at home, it was a joint decision. We have 4 kids. 20, 15, 7, 2. Oldest gone to college, comes home some weekends. Can't wait for 15 year old to start driving, will help out. Our 2 year old just started mothers day out, to give her a break. Costs money, but gives her sanity. 2 days a week, 5 hours a day. He loves it.
She's well educated, has a Masters in teaching. Did make good money before. She wasn't happy teaching anymore, it's not like it used to be. She would make enough to offset the kid care, and still be in the plus. It's just not worth it for us, and more importantly her.
A stay at home mothers or fathers job with multiple kids is almost always harder than the working partner imo. There is so much involved, always something to do. I routinely tell her how great she is doing. Because it can get lost in the shuffle. It's a damn hard job. I try to give her breaks when I can. Such as she's out for brunch with friends right now while I'm home with kids.
I would caution you to make time for yourselves. Not that you probably don't know this. Life can be busy, always something. School, sports, work, etc. We use the gym for "dates", drop off two youngest in kid care, and we get a glorious 2 hours alone to workout together. We don't have any family to help really, all parents in their 70's. All my family in 4,500 miles away so no help at all. So we rely on sitters and the gym. Sometimes have to be creative. Rambled, do what you need to do for you guys. Screw anyone else and their negativity.
