How has Solange Knowles, mother of 7-year-old Juelz and aunt to Blue Ivy Carter, adapted her everyday style since becoming a mom? "Comfort is becoming of real importance to me," she told InStyle.com last night, at a "Shop Spring" party held at Stuart Weitzman's boutique in New York City. "I find that the older my son gets, the more we have on our schedule, versus when they’re babies you’re kind of just going for walks and things like that," she said. "Now there are soccer practices and piano lessons and playdates and sleepovers and birthdays—comfort is definitely key," the DJ added. And what about baby Blue? "She’s kind of got her cotton Onesie swag going on," Knowles said. How cute! For more photos of Hollywood's hottest moms and their kids, click through the gallery.
