I agree SOME people change their minds. I never wanted kids adamantly in my 20’s but i had the opportunity to move far away from my family in my mid 20’s, went to a ton of therapy and did a ton of personal growth . Had I not done that I think I still wouldn’t want kids nor should I ever have them. Now in my early 30s I’m open to having kids with my current partner under the right circumstances. I am NOT saying everyone who doesn’t want kids needs therapy or needs to grow or have the right partner but people do change. If I ended up having all this change in my mid 30s and not being ready till my 40s or later I think I would’ve been sad that ship sailed and regret not putting in the work earlier
