“To Jayden and Preston,” the proud mama recently penned a letter to her boys. “You are my masterpieces. From the day I saw the most precious eyes, I believed in miracles to the core. Such a gift God has given me, exploring in your beautiful worlds every day.”

“I pray as a mother I teach you strength and passion to carry through the struggles in the world,” she wrote. “Most battles will always be won on your knees. I pray you find your dreams.”
