Rachel has built a truly unique modern family: instead of having children with romantic partners, she's searched for the best fathers she could find, and arranged co-parenting situations that benefits everyone. Jeff talks to Rachel about raising two children in this unique arrangement, and meets the father of one of her children, as well as a potential candidate for her next child. He also hears from the founder of a website that makes co-parenting introductions easier. Then, Jeff meets three women who all discovered they used the same sperm donor to get pregnant. They explain the relationship their children have with each other and the man who fathered them all. Later, Jeff talks with Esquire Magazine's "Fathers of the Year" - two men who have fostered 42 children over the past 10 years and adopted 12 of them!
