Rich Fury/Getty In the July/August issue of Vogue Singapore, Cardi opened up about her hands-on approach to parenting Wave and Kulture, revealing that she tries to ensure they stay humble despite their parents' means. "They need to know to never feel comfortable. Don't ever feel like, 'I'm going to get it because I'm Cardi and Offset's kid,' " she explained. "They are never going to know what struggle feels like, so they might not have that hunger I had to leave the streets." "Even though my kids are well-off, I want them to know that when you work for things and achieve it, it's more respected — especially when people see that you bust your ass for it," the "WAP" hitmaker noted.
