Time Out On Reproducing

I have always wanted a large family. My definition of large is 3-4 children. It would be so wonderful to have that many children and then each of them to have that many children and grow old with them (kids and grandchildren). Seeing the movie The Family Stone encourages this even more for me. I love that movie!! Watching the t.v show Arrested Development encourages this even more. There's nothing better than a large dysfunctional family!
But it takes two to tango and Jorge says he only wants two children. I told him if that is how he felt he better get "snipped," because I want more children. Even during those last few miserable weeks of being pregnant I went into labor wanting more kids.
During those last few weeks of pregnancy he went to the doctor for a vasectomy consultation, he came home as though he had seen a ghost. Those 30 mins traumatized him. Even though the doctor assured him that it was an outpatient procedure and would only take 15 mins. I think going online and looking at before and after pictures really ruined it for him.
After we talked about it I also had my doubts about the "snipage" that would take place. That would be a definite end to my child bearing days, no more beautiful children, no more feeling a baby move around in my tummy EVER.
It was too much for me to take in, so we canceled the thought of him getting a vasectomy ( I'm sure for different reasons) and brainstormed on other options.
Condoms? No, we all know that doesn't feel the same. Withdrawl method? Yea right, my luck I would have children 10 months apart, no thank you! Abstinence?  Lol-yea right, HE could never do that...I mean we. So I got an IUD the other day, the Mirena. Does it seem fair that I had to be pregnant for 80 weeks and then go through 2 natural births and then be the one who prevents us from getting pregnant again? Why do the women have to do all the work? Anyway, it was completely painless, took about 5 mins. She just placed the IUD on my cervix and we're good to go for 5 years. In 5 years I will be 33, wow!! Of course I can always have it removed sooner, but Hudson and Mia are going to have to be a little more self sufficient before I consider getting pregnant again. They need to be potty trained, be able to feed themselves and be able to bathe themselves...that would be nice.
I do still dream of a large family. But is it realistic when you have to have so much money to raise them? Especially big expenses like cars, colleges, weddings..etc. If it is meant to be it will be. Mirena is suppose to be 99% effective. What are the odds that I would be that 1%?
