Ok, so I was a bit pissed last night!
I can only talk about my situation however.
Yes, I would sacrifice my DH for my kids. I adore him, he adores me, but I grew my children, and nothing and nobody comes before them.
And reversing the situation, if a woman really didnt want children, Id expect her to have a coil/pill/implant, not just rely on condoms.
My situation is that Im a SAHM. I have no career/childcare costs. I have a few cars, one being a 7 seater, and we own a large home. In my situation, we dont need to consider loss of my work/childcare/space etc. Not saying its the same for everyone, but I can only speak for myself.
Now, if DH REALLY didnt want more, he would have the snip. He is a grown man capeable of making his own decisions. He just knows me too well, and grins at me when he says he may as well quit arguing now 
I dont force him into bed.
And he is a wonderful father, yet I do all of the day to day care. So really, the babies are my responsibility. Toddlers and children he is awesome with, but Im the one who gets up in the night, feeds, bathes, and meets a babies needs.
So, although I put it uber badly in my drunken state last night, I still kinda stand by OUR situation.
