"So proud of you and how you walk through life. I admire your compassion, curiosity, drive and fearlessness! Love you so so so much!" she continued.

Crawford shares Kaia and her son Presley Gerber, 24, with her husband Rande Gerber. In May, she opened up about motherhood while appearing on an episode of Christy Turlington Burns and Kelly Corrigan’s new five-part podcast series, Kelly Corrigan Wonders: About Your Mother.

When asked what the best piece of advice her own mother gave her, Crawford said one of her favorite quotes was, “Show up, shut up and wear beige.”

“It’s about when you’re showing up for your kids or… it would be more I guess if you were to be the perfect mother-in-law at a wedding,” the model recalled. “She’s like, ‘It’s not about you, you don’t want to stand out.’"

She added that the “best advice” her mom ever gave her was, “Don’t give advice unless [it’s] asked for,” which she does her best to implement with her own kids.

“They know if they ask me, they’re going to get my real opinion,” Crawford explained. “But if they don’t ask me… I really try hard, and I’m probably about 70 percent good at this… I try not to offer unsolicited advice.”
