“I had so many deep feelings about not being able to hold my daughter. When I first met my surrogate, we talked mother to mother. She showed me so much grace and understanding; I knew I had found a true angel. Words cannot express my gratitude that she kept our baby safe for nine months and made our dreams come true.”
Moon also revealed the meaning behind her daughter’s name: “I’m so proud of my little plum, my little dragon who made the journey to be with us. My heart exploded.” “Méi (pronounced may) means plum in Chinese 梅💜,” she explained.
In an interview with Vogue magazineMunn discussed her experience with fertility, mentioning that she froze her eggs three times — at ages 33, 39 and 42 — after being diagnosed with breast cancer. She expressed her openness to using a surrogate and her desire to continue growing her family.
“When you’re pregnant with your baby, it’s like teamwork — you and the baby are working together to make their little lives happen,” she said. “With a surrogate, you have to find someone you trust just as much as you do to live their life as a pregnant woman the same way you do.”
“This trip has made me realize how grateful I am to have options to not only fight cancer but also to have more children if we want, because I know a lot of people don’t have those options,” she added.
