I don't think you're going to get anywhere trying to convince a 3 year old not be obsessed with the things she's obsessed with. You're going to have a lot more luck "yes, anding..." her instead of "no, look over hereing".

The problem isn't that she thinks being pregnant is cool and stylish. It's your concern that she's hearing messaging that tells her that that's all that woman can aspire to in life. So make sure she hears lots of different messaging and sees examples of it and believes it.

Jacinda Ardern just wrote a kids' book about what it's like to have an important job and also be a mom: https://thespinoff.co.nz/books/04-10-2025/jacinda-arderns-new-kids-book-reviewed

Maybe see if you find more examples like that. Kids (and adults) can be obsessed with more than one thing at a time. Just because she's obsessed with pregnancy as a 3 year old doesn't mean she's destined to be in an abusive tradwife relationship. Maybe she's destined to be an OBGYN or an amazing kindergarten teacher or a child psychologist. Or maybe she'll combine having a big family with other major career goals. Maybe she'll be a great stay at home mom and that will make her supremely happy with her life. Or maybe she'll just get over it and move on to something completely different.

I'm the least maternal person on the planet but I went through a phase of shoving pillows down my shirt and imagining I had 16 kids. I didn't want 16 kids - I just wanted a big close family and I eventually figured out there's lots of different ways to achieve that that don't involve diapers, screaming and sleep deprivation. Watching Supernanny in my teens did the trick. So you have lots of time

But I think you should maybe examine your own assumptions that her interest in nurturing and pregnancy must be a negative thing. Kids that age are starting to understand sex and gender at the beginning of a long path to who they will eventually be and, unfortunately, you don't get to control how that turns out, no matter how you try. But the good news is, neither does anyone else completely.

As soon as I started speaking I refused to wear dresses or have anything to do with anything pink or female coded. One of my earliest childhood memories is the bitter disappointment I felt when a distant aunt gave me a set of toy cleaning supplies (brushes, mops, etc.) for Christmas. Surprise, surprise, I grew up to be trans man. There were no subliminal messages or gender-coded toys or social programming that were ever going to turn me into anything else.

I think the important thing is to teach kids to be open and honest with themselves and to give them tools to express who they are, not to try to steer them towards who you think they should be, no matter how well meaning you might be and then accept and love what you get because (for the most part) it's all good.
