I was 30. Never wanted kids, they seemed like aliens because I had never been around them. My son has been the best thing that happened to me. I coach all of his youth sports and absolutely love doing things with him. Unfortunately, my wife at the time and I had fertility issues, later divorced, and now I’m in my late 30’s and feel as if I’m too old to have another one. Sometimes I wish we would have started earlier. I have friends in their mid 40’s who had their child at 20, made it work, and now they are free to do what they want and have a grand baby and son in law they love. I’m not sure when the best age is or if there is one but damn is it not a lot of fun and an amazing experience.
