There are only two.
1. External uterus. That way, I can conceive the baby, put it in the uterus, stick it on a shelf somewhere, and go back to retrieve the kid nine months later. I'd get all the benefits of babymaking with none of the nasty pregnancy stuff.
2. Some method of getting breast milk from my boob to my baby, via a bottle, without the use of the kid's mouth or a pump. I figure this has to be possible somehow. My poor nipples just can't handle breastfeeding (which is partly the baby's fault because he's "lazy", according to the lactation consultant), and I really hate doing it. Pumping is just as bad. So, no more babies until science can provide me a way of getting the kid the benefits of breastfeeding without destroying my nipples.
