I would drink a lot at home. Wine. Just like a glass or two. And I'd feel better. And then I'd get the kids to bed and I'd drink like the rest of the bottle and start on another one. So a bottle and maybe a bottle and a half? I needed more and more to feel relaxed. Reporter: A brave and unexpected confession. Because from the outside harmony Hobbs was supermom. Oh, my god. I thought I was doing great. In a lot of ways on the outside it looked like I had it together. Reporter: But the Louisiana mother of three was also the ultimate wine mom. If there was an event leek a play date or if I had a birthday party to go to, it was okay to drink at that. And it's fun. Like all my friends were like oh, you know, that's hilarious. Reporter: Harmony even running a successful blog called modern mommy madness that celebrated cool moms who enjoyed their cocktails. But for harmony those meme-filled moments raechlg a dark truth, that life for her wasn't as happy without alcohol. People think they know everything about what's going on with me.

So I continued to drink more and more. Do you like mines, mommy? Yes. Reporter: Harmony saying the stresses of motherhood leading her to constantly fill her I had a very successful career in insurance, and I quit to be home with my kids. I did feel like I had the right tools to be a good mother. And that really bothered me. I drank because that's the only way I knew to cope with uncomfortable feelings. Reporter: Mommy wine culture, a narrate V playing out on screens big and small. From hit movies like "Bad moms" to Kathie Lee and Hoda. My wine's not tasting so nice. Mine's great. Reporter: Play dates on "Big little lies." What are you doing? Smoking. I hate smoking. Nobody smokes anymore. And moms' night out on the "Real housewives." Drinking behind some of the franchise's greatest and messiest moments. But experts warn the growing popularity of mommy drinking culture can mask alcohol abuse. I don't believe that you could say that a wine culture would make somebody an alcoholic. I would say that if somebody has a propensity to be an alcoholic this would be a perfect breeding ground to bring that out in somebody. But some moms across the country are speaking out. Like actress busy Phillips getting real about parenting on her 2018 cover of "Parent" magazine, saying "I'm so over the wine culture of mommy wine and glasses that say mommy juice." Harmony, joining that conversation, opening up about the toll drinking took on her family. You were angry. I was angry a lot. Alcohol made me more depressed. The unfortunate part is that my children and husband bore the brunt. How did you rationalize it in your head? Because you were a young mom. Well, I made rules that made it make sense. I would only have like a glass or two before Robbie got home. And then when he was home it was okay to like really drink. Were you worried about the children? I was never worried about the children because even at her peak at everything harmony is a very loving and caring, you know, for our children. And he didn't know how much I'd had before I got home. Reporter: But even at age 6 her oldest son maverick noticed mom's habit. Did you know she was drink a lot of wine? I did know that because I didn't know it was out of the ordinary because that's how I grew up, that's what I was used to. Every night she would grab a glass of wine and I asked her and she was like it's wine, it's an alcohol. And I was like oh, I heard of that in school. Doesn't that make you addicted to it? She was like yeah, but I'm not addicted. I don't know if she was trying to deny the fact she was using it as an outlet for stress. Reporter: From 2001 to 2013 alcohol use among all women in the U.S. Rose nearly 16%. While the percentage of women having four or more drinks on a weekly basis shot up by 58%. The pinking of the alcohol market being sparked by endless products like this mom's wine bottle glass. And mantras like mommy fuel and "I wine because my kids whine." Even commercial websites like etsy marketing toward drinking mommies. This is number one. Reporter: Harmony and best friend and writing partner Audrey Hayworth buying in. Because we want more alcohol. More alcohol. Reporter: The two getting a kick out of their YouTube drinking antics. Looking back, I can say that she drank more than I did. Reporter: Audrey soon realized that her friend was overindulging. I think we were filming three or four episodes. And at the end of it I still had half a glass of wine left. And she's like, you're not going to finish that. And I was like, okay. In retrospect now I can see she wanted to finish my wine. I was so deep in denial it never occurred to me that I was an alcoholic. Not once. That was a wake-up call. Reporter: The once comical mom transforming her blog about a painful journey on the agonizing road to recovery. It's ridiculous that at 37 years old I'm going to have to relearn how to cope with the difficulties of life, grief and pain and abandonment and loss and the everyday stress that accompanies motherhood. The hows and whys don't matter. I just want to get better. Reporter: Tell me about those first few days and weeks. I wanted to die. I really did. I thought -- I told Robbie if I can't drink I'm not sure I can go on. The only way that I knew how to cope with life was drinking. And if you took that away from me or I stopped, honestly I didn't know how to function. Reporter: Over two years sober, harmony is now discovering a shifting culture with some moms choosing to trade in their wine glass for wellness. Those joining the so-called sober curious movement, started by lifestyle journalist ruby Warrington who wrote a book about her sobriety journey. The by part of sober curious is to destigma nooiz the idea of sobriety and make it a much more kind of open and available choice for people. Reporter: Paola atlason a new York City mom of two is embracing this new movement as an alternative lifestyle to the mommy wine culture. I think the sober curious movement is challenging the mommy wine culture and I'm so glad it is.

Meditation, not rose, takes the edge of stressful days. Some of the benefits of quitting alcohol, are mental clarity is a huge one. And I would think just more joy. I just feel more joyful. I don't know if it's medication or the quitting the drinking, but there's a spark. I don't think everybody should fear alcohol because there are many people out there who don't have addictive personalities. There are many people out there who can go out to dinner and have a glass of wine and I don't think that everybody needs to stop drinking. I think it's always good to question your behavior. So you like the idea of people re-examining this relationship to wine all the time? Yeah. I think it's great. Reporter: Today harmony's play dates look very different. No alcohol.
