Announcer: We return to "20/20's" "with parents like these." Here's deborah roberts. Reporter: Taking a walk with mom is a challenge for lacey wildd's 17-year-old daughter, tori. Uh-oh, she's bouncing. When people see my mom with large implants, I feel like they judge me. Usually girls just like laugh at her, make fun of her. Men calling out. My life revolves around her boobs. Reporter: Every moment, tori keeps a wary distance. After all, it's not easy living with a mom who's 52-inch assets are on clear display. It's annoying. I feel like we should have a normal time walking down the street. I wish she could take them off when we go places together. Reporter: Lacey wildd is all about living large. Very, very large. Much to the dismay of her son brandon. Everything's fake, I think. I don't think she looks good at all. I think she looked pretty before the surgery. Reporter: Lacey claims to have the seventh largest breasts in the world, a way to support her family from public appearance fees. But those volleyball-sized breasts are also the source of bitter conflict between mother and daughter. People will start booking her kind of like, you know, when you go see the two-headed man, you know. It's not ley're booking her because "oh wow, she's like sexy." Thank you dear, I just love you saying that. She's basically saying I'm the sideshow. Reporter: Lacey's work on her website also cuts into mom time, according to her younger kids, genevieve and brandon. She's always busy on the computer. Her phone. Ipad. She never does anything with us. I just got asked to do, go to the grand opening of a day care because they want the dads to get involved. Reporter: So how much do you think you'll make, because of those breasts? I'm looking maybe to make $250,000. My boobs are my paychecks, for sure. Your boobs are your paycheck? A hundred percent. Reporter: It wasn't always this way. Lacey started life as a tomboyish girl next door named paula. I was just a flat-chested, brown-haired little girl, from a midwest town. That's the house I grew up in. I slept on the floor. I don't think I'll ever be that poor again. Reporter: Married at 16, divorced with 2 kids by 21, she was scraping by as a waitress when suddenly she had a big idea. I changed my hair color, and I got my breasts done, and my money just started rolling in. Reporter:12 breast surgeries later, good-bye paula, hello, lacey wildd. But being lacey comes at a cost. She can't even pick up her 5-year-old daughter. It's not going to work. I can't lift her up and pull her to me, because let's be honest, I'm out pretty far. I can't work out. I can't jog. We used to ride bikes together like every night, and we can't do that anymore. Reporter: Sleep, too, is a difficult balancing act. She has to have a pillow on her boobs. Yeah, she has to have like, three pillows under her boobs. After a little while, I can't take it anymore. I feel like I'm being suffocated. She sleeps like this. Like a mummy. Reporter: Lacey's kids endure a much greater hardship every day -- the scalding shame of public embarrassment. My mom walked in to drop me off at school, and this kid says -- "your mom has big boobs." That made me feel so crazy. So weird and awkward. Yes. I do want my kids to be happy and not be embarrassed of me, be bullied at school, or feel embarrassed at all. Reporter: So at home in sunny south florida, lacey sometimes goes to great lengths to come off like the mom next door. Extra large pants, extra large jacket is required for this operation. So, look, normal mom, right, in 100-degree weather. Reporter: Nice try, but not good enough for 11-year-old brandon. I want her to get them smaller, not stay the same or get bigger. And then I would be happy. Reporter: Well, get ready kids for a new round of zany. Lacey is about to double the size of her breasts, going from a triple "l" to a triple "q." If she gets bigger, it would be chaos. They'll be like, forty-two pounds. Reporter: Is it safe? Absolutely not. These aren't safe. I'm a walking time bomb, is what the doctor told me. Reporter: The surgery is so risky that no american doctor will do it. Tori is outraged that her mom is willing to take that chance. What if she died, is she really taking that into consideration? Does she care that her kids could be left alone? Reporter: But lacey's fans urge her on, donating for her upcogery in brazil. You know, when people like put on that internet, like, "oh, I'm gonna kill myself. I'm gonna do this." People -- like, "do it, do it, do it," because they don't really care about you. They just wanna see you do something crazy. And then they're done. So are you gonna do it? Well, I haven't done it yet, so -- and that wasn't what I asked. Reporter: Your daughter tori is really upset with you. She's -- thinks that I'm, I'm being irresponsible, by putting my life on the line. Reporter: If you, you say it's upsetting, I feel bad, i don't want them to be upset, but why do it? It's the money. It's the money. I need the money. Reporter: Money to send tori to college and care for her two younger children. There are people who are working two jobs, at a grocery store and a department store. I was doing okay. But I quadrupled my income. Reporter: Do you ever regret this? Um, no, actually, I don't, i don't regret it. I would do it again. Absolutely. Reporter: Even knowing that your kids are upset and embarrassed? Don't our parents always embarrass us? The other day I went to a party and this kid came up and he's like "are you tori, the one that has the mom with the big boobs." I'm like, "yep, that's me." Reporter: Do you think that this could permanently damage your relationships with your children? I don't think so. My kids love me for me. I'm very loving. My heart's bigger than my boobs.
