... and I've thought that if I were to have I kid without a mom around that I'd want someone to breastfeed for me.
Do you mean the mother is not around by choice... or because she is no longer living? If she is no longer alive, I agree with you to get someone to give your baby breastmilk instead of giving her cow milk or fake milk alternatives. However, if the natural mother is still living, you should have her breastfeed the baby (assuming she was healthy enough to bear children, she should be healthy enough to lactate), because a mother's milk is designed specifically for her baby. The consistency of mother's milk varies from morning to afternoon to evening to night, giving the baby exactly what she needs at all times. In other words, mother's milk "knows" her baby and "knows" her baby's exact needs. I know you have suggested you are not interested in a romantic relationship with a woman, but that does not mean that you cannot co-parent and allow the mother to breastfeed the child. After all, once you bring a child into the world, your purpose is to raise that child well, and your needs and desires become secondary.
As far as who's taking care of me I don't think it would matter what 'kind' of person, as long as it was a person who loved me and was responsible/intelligent enough to do what's right for me.
And, the responsible-intelligent-right things would be to breastfeed, and to consciously and carefully nurture the child's moral, intellectual, social, and physical growth... I believe the best person for that is none other than a mommy! All others, while they still may do a good job, their abilities still come in second to those of a true mommy.
I do think daughters need fathers as sons need mothers, as daughters need mothers as sons need fathers... but this is a totally new discussion; you're right. Let's start a new thread elsewhere.
