But Channing Tatum is really taking to it the next level. Tatum, whos played action heroes and perhaps most famously a male stripper, recently traveled deep into the south american rain forest for an unusual sort of market research. And he brought along abcs Rebecca Jarvis. Reporter deep inside the rain forest of ecuador i find myself dancing. With a group of amazonian women. To it. Reporter the actor once Channing Tatum. You. Whoo reporter were here for a ritual thousands of years old. It smells so good. It does, right . Reporter the key to what people begin every day like mystical quyalusim. Oopie they got up before the light, started drewing, and they do it to create community, to talk to their young, and the elder pass on the stories, can pass on their knowledge. Its kind of magical, the whole thing. It really is. Reporter in the United States quyusa is packaged and sold as runa. A drink channing says became his stamina secret while working on magic mike. I was going through about six to seven cans. We were exhausted. Magic mike surviving on runa . Thats it. Our blood was runa. It became an obsession. Reporter now channing says runa is an essential part of his life at home with wife, actress jenna dewan tatum, and daughter. I dont drink coffee, it gives me the shakes, that anxiety feeling. This is my everyday. I get up and me and my wife, we wake our daughter up, we start our day. Thats just what it is for us. Its the tatum tea ceremony. Thats right. Reporter runa is marketed as a clean energy drink, differentiating itself in a 50 billion industry. The company says one bottle provides the same stimulating effects as a cup of coffee. With the added benefit of 15 essential amino acids. It has caffeine, it has antioxidants, gives you great functionality, you can feel it. Reporter thats tyler gage, the man responsible for bringing this tee to the masses. He first tasted it 11 years ago while visiting the amazon and believed so much in its potential, he built a company around it. I showed up in ecuador with this idea of using it commercially. The farmers literally laughed at us. The idea of commercial was nil. In only six years weve grown to support over 3,000 families. Of direct cash income to the communities. Theyre not laughing at you anymore . Theyre laughing in a different way. Reporter two and a half years ago a business adviser caught wind of channings love of runa and recommend the tyler reach out to see if channing might invest in the company. What was that first meeting like for you . It was funny. Because this friend of neils asked if i wanted to meet a guy named date ed d ed d ed d tatting channing. I thought they were joking. That was a character i played. This is tyler gage. Turned out hes a real person. Here i am. He happens to be way smarter than i could ever try to be. Reporter already a runa megafan, channing was in. And while clips like this on lip synch battle may go viral for a impact. So we traveled far into the jungle. By car. Hola reporter and by foot. Appreciate it. Welcome. Reporter to see firsthand how this ancient leaf is making its mark on the world. Ruth is just one of 3,000 farmers who supplies quyusa to runa at a fair trade price. She said now with selling to runa theyve been able to take this important part of their culture, share it more broadly, use it to materially support their families. Where are we going now . Up to the runa factory. Reporter channing and tyler take to us runas headquarters where all those leaves end up. Hey this is it . This is it, this is the dream. This is the worlds first quyusa factory, exporting from the amazon. Lets take a look around. Lets do it. Cool. Called withering. The process where the flavor sets into the leaf. In this space you say theres how much supply of runa . We probably have a month, month and a half supply worth of runa. Thats a lot of runa. Reporter the leaves are laid out on drying beds. This is where the moisture gets down to 2 . You can feel the heat in this space. Id say its about 100 . Probably about right. Reporter then sifted and packaged for delivery. 100 organic, fair trade, and nongmo. This is what it basically gets packed into. Thats perfect. Reporter before its shipped to the stores, theres the essential taste test. Run by daniel in this lab. Mmmmmm i feel like its going to come out my nose. Thats the kind of thick you shouldnt say. I always say among the 70 people of runa, daniel has the funnest job by a long shot. Have you seen the movie whatd you think of that guy . Come on. Back to work. Sorry, i had to. Reporter back at the tea ceremony, we learn theres no limit on refills. How many cups a day do you drink . I dont think in gourds, i think in pots. I drink two to three full pots a day. He said in the culture they traditionally have lots of kids. And its part of the quyusa. Gives you strength and virility. Life force to carry forward. Thats how i got my kid. Now i understand. This experience of just being a part of this tea company has enriched my life to a degree that i dont even know if i can express it. I grew up in the south where i was 7eleven culture. You know, mcdonalds culture. Was tasted good. Theres something beautiful about knowing where this is coming from and what the story is. Theres an intentional consumption that i believe is really where i hope that societys going. Reporter what do people say to you when you go back home, tell them about your experiences here . You know, its hard. You know, its hard to see a bunch of pictures and hear some stories and really understand it. And so i give anybody an open invitation to come on down. Really . Youve got to be careful. Youre saying this on nightline. If anybody has a lot of money and they would like for me to host a tour, i would totally do that. So there is a price. Im buyable, straightup purchasable. Reporter ladies, take note. For nightline, im Rebecca Jarvis in ecuador. Next, why Kim Kardashian says going from one kid to two kids has really been a difficult adjustment for her. Tonight the backlash and the much for some people .

Now kim has come out to say that has been genuinely tough on her. Not everybody is sympathetic. Her comments have generated some real dialogue. Heres abcs reena niner. Reporter not many parents with two young kids spend their nights like this. At a mega fashion show in new york. But thats just what kanye and kim did tonight. Seen here in this video from title. Even with all the help she can afford, kim now saying baby number two has been a big adjustment. Posting this week, i get no sleep. In reference to balancing the needs of her newborn son with those of her toddler daughter north west, seen in this instagram photo. Every waking second im not with the baby im with north. I feel like i go into overdrive to give my daughter attention and make her feel loved. Of course as the internet was quick to point out, she probably has lots of help. But there are the sympathizers too. Kardashians comments sparked new dialogue about being a parent in the modern age. To two or more, the pressure to provide a perfect upbringing for each one has made parenting harder than ever before. It can look a lot like this. Corey white and her husband dan gibson are parents to four kids. This is levi. Olivia. Jackson. And then we have emily. If you can see us all. Reporter earlier this month the couple posted this video to facebook. Showing the ontario mom juggling to put her toddler and three young triplets to bed. The post quickly racked up over 66 million views on facebook. Finding out they were expecting triplets was a total shock for corey and dan. I went to the ultrasound by myself. And when i got there and they told me it was triplets i didnt know whether to laugh or cry. Reporter but sometimes life works that way. Just ask Nicole Mcnamara and her husband melvin. They had one son, melvin, named after his father. And decided to go for one more. We got together, we decided i mean, that was kind of the number we were hoping for. Easy. Reporter instead they got these guys, twins hunter and skyler. We went into the doctor and he said, well, theres two. And my response was, two what . She was like, two babies. I was looking at the screen. I said, yep, i can see two. Like a National Geographic of animal. Yeah, theres two there. Kids isnt cheap. The average cost for middleincome families to raise a child in the u. S. Is more than 245,000. By the time their kids are 18, nicole and melvin will have spent more than 736,000. And they havent even paid for college yet. Child care is extraordinarily food. Food is a biggest expense. Reporter its not just everyday costs that add up. Those untenable expectations. A study shows that 53 of moms create perfect life for their children. And 46 have incurred debt as a result. Its not uncommon for parents to put their kids first. And even put themselves in debt in order to provide certain opportunities. Reporter this idea of perfection is taking a toll on more than just the bank accounts. 44 of moms say they argue with their partner over money. At least some of the time. The percentage jumps to nearly 50 in households with two or more children. I think the more personalities you have in the household, the more conflict there will be. And every parent has a different way of parenting. Reporter and when it comes to having that second child, women and men appear to have different experiences. According to studies, women and men differ slightly in happiness after the birth of their second child. We have a lot more women who are in the work force. And a lot more women who are, you know, earning the living and then on top of that, they want to be the good mother, the good wife, the good friend. Reporter even if its hard, almost every parent thinks raising children is the most especially if theyve had trouble conceiving. On tlcs new show rattled oh, hi, baby. Reporter firsttime parents ashley and Tyson Gardner struggle with infertility for eight years before giving birth to two sets of identical twins, a 1 in 70 million chance. Just having them makes us appreciate every moment. Especially having quadruplets. Where some people may not be super grateful for such a hard situation, for us were like, yay were so excited. Like they all four have poopy diapers and were like, this is great we are just running a million miles an hour. Constantly. It is very expense ive. Wipies, medicines, doctor visits. Mutt fly that times four. Sometimes youre spinning into the ground. Reporter seeing they were overwhelmed by the challenge of raising four babies, ashleys sister turned to the internet for help. She helped the gardners set up a Facebook Page and blog called the gardner quad squad which helped the couple with donated baby clothes and supplies. Thankfully for the mcnamaras the newborn phase is behind them. The twins turned 3 in may. Its no walk in the park. Both nicole and melvin work fulltime, mostly from home. Work is always here. After the kids go down we go back to our offices. We have to be intentional about saying, okay, this is the kids time, this is our time. Reporter these parents all say they wouldnt trade it in for the world. Everybodys going to have their ups and downs, their struggles. But children are the greatest blessing ever. No matter how hard the struggle is with them, theyre worth every second of it. Im reena ninen in new york. Our thanks to reena.

Dont stop cant stop this music video shot entirely in zero gravity is racking up millions of hits tonight. Dont stop cant stop the song is upside down and inside out. The band is ok go. The video features the band members and a few dancers in Flight Attendant uniforms performing stunts while flying in a plane thousands of feet above the earth. It is truly unbelievable that everything just came together. Reporter it required three weeks of training at a russian cosmonaut center. We flew in a plane that basically goes like this. Wonderful is 20 seconds of double gravity while the plane is throwing you into the air, then you feel weightless for 27 seconds while you go up, over the top, and sail back towards the ground. After the maneuver youve lost altitude so it takes four or five minutes for the plane to gear back up to do it all over again. We wanted the whole video to be weightless. We cut up the song into eight into a single period of weightlessness. Wed perform them in order, then later cut out the four, fiveminute waiting periods. Reporter ok go is known for creative videos. Here we go here we go reporter they ran their way into the National Consciousness more than ten years ago with here it goes again. Then they turned a car into a Musical Instrument for their needing getting video. I wont let you down reporter and they wowed with these impressive aerials in i wont let you down. Upside down reporter this shoot presented some very specific challenges. Most peoples response to weightlessness is to start swimming. The other is just puking.
