Some people just don’t fancy the idea of having children – and it’s that simple.

Despite knowing their lives are better without kids, society seems to still have a strong opinion on the matter. Those brave enough to discuss it online could often get into quite a debate.

Now Karina Irby is one of those people who still to this day, has to explain why she doesn’t want children. The body positivity star boasts 1.1million followers on Instagram.

The Aussie isn’t just any bikini model, she’s also the CEO at Moana Swim and isn’t shy about sharing her life online. Recently, she started a Q&A on her Instagram stories – and the baby chat cropped up again.

When quizzed: “Do you plan on having kids?” Karina clapped back with a snap of her and her hubby: “Nope. Children by choice couple over here.”

Later, as she dished out the deets on her bikini world, the kiddie question reared its head again. Someone piped up: “You will retrete this decision if you don’t have kids [sic].”

Karina wasn’t having it, firing back: “Regret* How can you be so sure I’ll regret it? You don’t know me or my husband? I’d regret having them.”

The influencer and her other half Ryan have been crystal about not wanting children – and their simple reason is because they’re happy without them.

And it’s not even the first time she’s had to put her foot down. Previously, she revealed how strangers get mad when she tells them why she doesn’t want to become a mum.

In an honest video, she explained why she doesn’t fancy being a mum. She reckons she often “upsets strangers”, because she’s dead set against the idea of having little ones in the future.

Karina was chatting to a “really nice” lady who clocked her wedding ring. As they got talking, the woman was totally gobsmacked the influencer wasn’t interested in starting a family.

She said she watched the “blood drain” from the woman’s face when she dropped the bombshell. The reaction was so over the top, she knew she had to tell her followers about it.
