Of course abc news will stay on this breaking story throughout the night. But we are going to shift gears now in a major way to what was going to be our first story tonight before the breaking news out of louisiana. A cultural story and a controversial one at that, about an unusual modern family featuring two moms and one dad. They call it polyamory and abcs Abbie Boudreau has more. Reporter oh, the sweet sounds of morning. As a new parent. The bed you once shared with your partner now a little more crowded. And all the more so when there are three parents in that bed. Ill take care of it. Reporter meet the phoenixsteins. Dani, melinda, and john. And their babies ella and oliver. Born just five weeks apart. These two moms and one dad are polyamorous. If youre not a couple, what do you call yourselves . Were a triad. Some people say a triple. I like that one too. Reporter this triad wants to make it clear they are not polygamous like the families made famous in big love. Hello . What do you think youre doing . Sleep well . Reporter and sister wives. We have one man and two wives. So how is this different from polygamy . Polygamy is one man with two women who the women dont share necessarily a relationship together. Polyamory, everyone is openly sharing love with one another equally. Reporter for them its about sharing parenting responsibilities equally too. Balancing work life and family time. Theres almost always a parent present with the two children. Theres just more parental support for having the children. Its always one of us that is able to be present. Reporter a Strong Family unit has been the goal since exchanging vows in an intimate threeway wedding ceremony last year. Im married to jonathan. Hes my husband. Im married to danielle. Shes my wife. Im going to be committed to them with my heart and my body. Reporter although the union is not legally recognized. If marriage is defined by something legal, then were not married. But marriage means something deeper than a signed piece of paper. Reporter in a time when attitudes about marriage are shifting. Last month the Supreme Court handed down this historic decision. That the United States is now a nation where gay people can get married. Reporter prompting some from fox news to ask, whats next . So suppose three people, say we want to be a marriage, whats to prevent that under this . Reporter the phoenixsteins are hoping, nothing. And theyre pushing their definition of family with the web series looks like love to me. Seem at little bit you know, every time you guys leave together and it hurts because i feel like im missing out on that family time. Who wrote the formula of one man, one woman, and two and a half kids . Were trying to be the pioneers, like in the civil rights movement. Reporter this trail blazing triad began as a couple. After four years together, dani and melinda were in a slump. Melinda felt something was missing. A man. When she brought up this idea about having a man brought into your relationship, you guys were already legally partnered. She was very direct. Like, i want a family, i need a man, and we need to make this happen. I need a man . Yeah. Reporter to make it happen, they both had to agree on the right guy. Making a list of their ideal qualities in their future third. What were the most important things from that list . That he was masculine. We didnt want a feminine man because were both very feminine. In walks jonathan. Were like, wow. All of a sudden were recognizing this beautiful man. It was very exciting. In the very beginning there was a lot more of three people having sex together. Often. Our bedroom, our gigantic bed. Oh my gosh. Threesomes totally happen, obviously less frequently now that theres kids. As exciting as threesome sounds its challenging to focus on one person and try and make sure youre including the other person. Its not only about sex. Its about family, its about working together as a team, its about accomplishing your dreams. Reporter one of their dreams, having children. And they managed to do that all together too. Ella and oliver are just five weeks apart. Its one thing to have your relationship and have it exactly how you want it. But then to bring kids into your relationship. Do you feel like its a healthy way to raise a family . A resounding yes for me. Yeah. More breastfeeding, more opportunities, more teamwork. I can double breastfeed while melindas making food and john is doing whatever it is. Reporter were tagging along with the phoenixsteins to attend a barbecue to meet other polyamorous people in the community. So whats it like to have two wives . Its great. Yeah. Reporter among some of the diverse attendees, 69yearold ann valliant. She says polyamory is far from new. Its new to people who think the only way things are is one man, one woman. But that has not been true. Do you think that people would be surprised how many polyamorous people there are . I know it. Which was harder to come out as . As a lesbian or as a polyamorous family . People nowadays are willing to accept the queer community. Its almost not a big deal. Theres a huge poly community but unfortunately not many of them feel that they can be open. They have to be closeted. That goes to show you its harder to be poly than gay or lesbian, i think. Reporter these relationships can be inherently tricky. Theres times ive felt i needed more and im not getting back. Then that comes up in conversation. Reporter remember, melinda was the one who initially wanted to expand their partnership. Does it make you feel frustrated or angry . Yeah. Theres been times where ive felt, you know, melinda has her guy and she has a girl. And john has two women who hes attracted to. And i have a guy whos really fun and i have a girl whos pretty much straight. Wheres my sugar on top . Was there a tad bit of you that might feel a little guilty that shes not maybe as fulfilled as you are in a sexual way . No. Just because were always in communication with it. If it got to the point where she felt that she wasnt getting her needs met, then we would address that. I think our lives naturally created what we have now. Reporter for now they are not planning on expanding their triad. But its not off the table. The family unit comes first. Right now we just wouldnt even have enough time. You know . To date anyone else. Whats wrong with seeking your own happiness and your own fulfillment with love . Shouldnt we all be in a space where were happy . Were not saying that polyamory is for everyone. Were saying, lets open a dialogue that theres other ways to do this. Reporter for nightline, im Abbie Boudreau in oakland, california. Up next, something completely different. Were going to a Demolition Derby where some of the most aggressive drivers will probably surprise you. Aggressive drivers will probably surprise you. What about my family . My lil buddy . And what if this happened again . I was given warfarin in the hospital but i wondered if this was the right treatment for me. Then my doctor told me about eliquis. Eliquis treats dvt and pe blood clots and reduces the risk of them happening again. Not only does eliquis treat dvt and pe blood clots but eliquis also had significantly less major bleeding than the standard treatment. Knowing eliquis had both. Turned around my thinking. Dont stop eliquis unless your doctor tells you to. Eliquis can cause serious and in rare cases fatal bleeding. Dont take eliquis if you have an artificial heart valve or abnormal bleeding. If you had a spinal injection while on eliquis call your doctor right away if you have tingling numbness, or muscle weakness. While taking eliquis, you may bruise more easily. And it may take longer than usual for bleeding to stop. Seek immediate medical care for sudden signs of bleeding, like unusual bruising. Eliquis may increase your bleeding risk if you take certain medicines. Tell your doctor about all planned medical or dental procedures. Eliquis treats dvt pe blood clots. Plus had less major bleeding. Both made switching to eliquis right for me. Ask your doctor if its right for you. Do you like the passaaadd . Its a good looking car. This is the model rear end event.

That was a really big accomplishment for me. Lets start stripping. Ive been doing Demolition Derby since i was 19 years old. My dad has done it since before i was born. Reporter her two sons, 14 and 8, already behind the wheel. Do you have a license . Not yet. Reporter her uncle runs metal mayhem every year. Are you ready .

Reporter kim is getting revved up for battle. First up, the rule is you never quit. Reporter they may call this the powder puff heat. Theres nothing soft and dainty about it. For vicki, a serious glitch. Exactly what she was worried about. Her drive shaft fails. Her car is a sitting duck. The minute he said go, i made one hit and was done. I was devastated.
