I was thinking about the possible issues with breastfeeding and how the aliens on the generation ship are anti formula. So I think I have come up with a solution that doesn't involve any formula whatsoever. Here are the potential issues with breastfeeding: Low milk supply Overproduction Medical issue with the mom Baby too premature Mom just won't breastfeed Of course, if the baby is too premature for direct nursing, then either IV nutrition or an NG tube would be given and if the NG tube is given, the mom can connect a breast pump to the NG tube and if an IV is given, the mom can pump breastmilk and store it. Low milk supply could be corrected with either a lactogenic treatment(increased lactation) or supplemental breastmilk from donors. A woman with an overproduction issue would be a great breastmilk donor. Now, I was thinking that if none of these 3 previous issues is the problem, then depending on whether it is medical or personal, the mom should be treated differently but the baby should be treated the same. The baby would either be: Fed by a mom that is already breastfeeding Fed by a young woman who has induced lactation Or in WCS, fed by an alien who is lactating. For women with a medical issue, lactation should be stopped as soon as possible. For those with a personal issue, they should donate breastmilk. But is my reasoning about breastfeeding issues and how to solve them logical for a generation ship where the aliens are very anti formula? Or is there a fault in my logic somewhere?
