In honor of Mother's Day this Sunday, supermodel (and supermom) Heidi Klum shared some words of wisdom for new moms in a new video—including advice from her own mother! "My mom gave me lots of advice. The biggest is to always have fun," the mother of four said. "Just have a great time with it. It's such an amazing experience." When it came to her personal experiences with new motherhood, the German beauty got lucky. "All my pregnancies were easy—I didn't have too many cravings or weight issues," she said.
