Millie Bobby Brown talks about her daughter for first time and explains why she'll never reveal her name

Millie Bobby Brown has been tight-lipped about becoming a mother until now.

The Stranger Things star, 21, adopted a baby girl earlier this year with her husband Jake Bongiovi, 23. The couple first announced the happy news on 21 August via Instagram, writing: “This summer, we welcomed our sweet baby girl through adoption. We are beyond excited to embark on this beautiful next chapter of parenthood in both peace and privacy.

“And then there were 3. Love, Millie and Jake Bongiovi.”

She posted a carousel of images in September, and the snap that garnered the most attention from fans saw Jake holding a baby carrier, presumably carrying his and Millie's baby, while walking towards a plane.

As the final season of Stranger Things inches closer, Millie has spoken about motherhood in an interview for the December issue of Vogue.

When asked about the new addition to their family, Millie gushed: “It’s been a beautiful, amazing journey — she’s taught us so much already.”

She also noted how her views have changed, saying: “Perspective is a huge thing. The smaller things in life are so much more precious.”

“Our days are filled with lots of cuddles and laughter and love,” Millie added. “It’s just endless joy.”

And when asked who's on 'nappy duty most', she answered: “We are 50-50 on everything. That’s why I’m so grateful to have partnered with him in this life — he is just the most amazing dad.”

However, despite sharing a few cute tidbits about life with their daughter, Millie said she has no plans to reveal details about the little one’s personality or her name.

The Enola Holmes star said: “I’m not going to,” when asked to talk about her baby’s personality, and offered an explanation for her decision.

“For me, it’s really important to protect her and her story until she’s old enough to potentially one day share it herself,” she explained.

“It’s not my place to purposefully put her in the spotlight unwillingly,” Millie added. “If she chooses to share her personality one day with the world, like I did when I was young, that’s something we’d support. But right now, as she’s so little…”

After a pause, she continued: “As her parents, it’s our job to protect her from that.”

The name of the couple’s daughter will also be kept under wraps for the foreseeable future, with Millie stating the public will know once 'she’s ready to decide for herself'.
