If you want kids, don’t put it off for too long. I waited till my late 30s because I was never ready. Here’s the thing you will never feel completely ready. As long as your life is basically stable (job, housing, and no serious issues) you will be okay.
Kids are hard but super rewarding. If you have them young then you’ll get to see them as adults in your 40s. By the time my kids are adults I’ll be pushing 60 and hoping that I live long enough to meet a grandchild.
People have successfully (shades of grey here I know) been having kids for a long time. You’ll never feel “ready” but rest assured you’ll figure it out.
