Millie Bobby Brown wasn't prepared for the "overwhelming" and "incomprehensible" love she would have for her daughter.

The Stranger Things actress and her husband Jake Bongiovi adopted a baby girl in 2025 and the 22-year-old star admitted she didn't expect the huge wave of emotion that has engulfed her.

Speaking to UNICEF in a clip shared to Instagram, she said when asked for one thing she wasn't prepared for about parenting: "The love. People say they love their children.

"I couldn't--I don't understand how that much happens in my heart. The feeling is so overwhelming. It's just incomprehensible."

Millie is thankful she can always call her mother, Kelly Brown, or Jake's mom, Dorothea Hurley, if she needs some support or advice with her daughter.

She said: "Naturally, just when you see something, like they're doing something, you're like, 'Is that normal? Do they do that?'

"And I call my mum, she is just like my 9-1-1. It's like, 'Mum, did I do this? Did my siblings do this?' And she's like, 'Oh yeah, that's completely normal. They do that all the time.'

"It's so great, I'm so honoured to have support. And if I can't call her, I call my mother-in-law. And she is just like the same way. It's just so nice to hear reassurance."

The Enola Holmes star tries to keep her family life private, but did reveal she and her daughter, whose name she hasn't made public, love to eat together.

She said: "She loves food, and I love food. So, our love language together is food. We just love to sit there and eat. And she always wants to try what I'm having, and I'm always eating what she's having."

Millie feels a "responsibility" to raise a daughter who wants to support other females and doesn't give in to inequality.

She said: "Raising a daughter is a real responsibility.

"I just try to learn as much as I can and feed it into her life so that she knows nothing other than girls supporting girls, or women succeeding, women achieving their dreams, and living in a world and building a world for her that isn't unrealistic, but it sets a standard for her to know that she shouldn't settle for anything less."
