How Many fathers are Best for a Child?

the Bari version of conception is that a child can have more than one father. as Rachel describes "a fetus is built up over time with repeated washes of sperm" meaning that more than one man can contribute. groups across South America and other cultures across the globe all expect one mom and one dad to be the beliefs in every culture. they do believe though that the first act of sex should be between a husband and his wife, and that plants the seed. they say the fetus then needs to be nourished by repeated anointings of semen.
in their culture a woman's body is viewed as a vessel and men do all the work. they claim its hard work for men to support a pregnancy by having enough sex. they believe in lovers being okay to have and are used so their husbands dont get wore out.
unlike in our culture where both mother and father have long-term economic responsibility, and when a parent fails to provide for a child its a violation of law. in their culture when a man is named as a second biological father they are obligated to the mother and child and are expected to gift them with fish and game.
researchers recorded 916 pregnancies out of 114 women an average of 8 pregnancies for each women. about 1/3 did not survive to age 15 . seondary fathers were involved in 25% of pregnancies.
children with 1 father and one second father made it to their teens, but children with 1 father or more than 2 didnt last as long.
the Bari believe that the best way to cure a sick child is for the father to blow tobacco smoke over their child's body. in their culture and kinda in ours it is essential to have a wife for economic necessity to harvest, manioc farming and cooking while the men would hunt and gather. in our culture the women are expected to cook and go out and buy the food and keep the house up.
1/3 of 122 women were faithful to their husbands during pregnancy. humans are naturally monogamous forming nuclear behavior. i totally agree. i grew up expecting every family to have one mom and one dad and that having lovers was wrong.
in China a father leaves and has nothing to do with the child or family. children grow up at home with their mothers and siblings and they stay there for life. the father has no responsibilities toward the child, so pretty much they are just sperm donors.
