There are many reasons we will probably stop at 1, even though I ponder the question often.
I thought that after 3 days of labor and 10 hours of pushing through what turned out to be an oddly shaped pelvis, that my midwife would say Never Again. But when I asked her she said, Oh, the tracks have been greased!
What feels like one of the biggest reasons for not having more children also seems like one that shouldn't matter as much as it does. Many other courageous women in my position have gone on to have many more children, but I think I'd go crazy if I had to go through my low milk supply thing again. Call me weak. (I would not count on being able to breastfeed after a second pregnancy.)
The experience of ot being able to breastfeed as much as I would have liked, and all the associated junk, threatened to rob me of much of my enjoyment of Dd's infancy. I refused to let that happen but it was a tough battle. Now that Dd is almost 15 months old and my (essentially full time) efforts have resulted in a wonderful breastfeeding relationship, I would hate to cut it short by having another baby. After all we've been through, Dd loves to breastfeed, and I just can't see ending it before she is ready.
Sometimes I think I'm allowing myself to be doubly hurt by this, pain with Dd and not allowing myself another child because of it. But there are other reasons too. This one just looms as the largest.
Other reasons include, yes, the environment. Also I am the kind of person who has always focused on doing just a few things at a very high level. I worry that with more children I would feel spread too thin. I still hold Dd for all naps. I need a lot of sleep that I get by doing this. I want to continue this for as long as she is in need of this.
Our finances are comfortable at this family size, and to add to the family would mean more work hours for Dh. What's the point of having more children if he has to take more time away from home to feed them?
I've thought that after Dd weans herself I might be willing to consider another pregnancy, but I don't think I have many fertile years left.
But we are very happy. Our family is very cozy. I understand that love grows and I'm sure it would if we had another child, but right now I think it would be hard to be drawn away from Dd. Rather than have another child, we are concentrating on the one we have, reveling in her every moment. Dh thinks that Dd will consider her family so great that she'll never want to leave, and he hopes that is the case. I guess I worry that she'll feel so focused on, she'll choose the most distant college she can find and live in Europe for 10 years to get away from us.
