An increasing number of Australian men are choosing to be childfree, and climate change, financial concerns and prioritising adventure are some of the reasons readers shared with us. We heard from child-free men after publishing our story on why more men are turning away from fatherhood.Here is some of what some of them had to say.My choice to be childless is much the same as described in [your] article — fears of passing on my own mental health issues, seeing how having kids impacted my father's life negatively, and barely being able to afford to keep myself afloat, let alone the added cost of kids.My brother had three kids and it's more important to me to be an additional safe adult in those kids' lives I do not and have not regretted this decision.I am not huge fan of children.I have been married to a wonderful woman for 30 years who feels the same way as I do.We have lived a carefree and adventurous life and [have had] opportunities that would not be possible for families without big dollars.— Jarod (not his real name), aged in his 50s, TasmaniaI have experienced the raising of eyebrows many times as if I have committed a sin or lacking some kind of capability of commitment.At my previous job my manager told me I could be more patient and that I was not because I don't have a child.I get a lot of comments from my friends that compare my dogs to children as if we have them because we can't have children
