Since having kids is so tiring in the early years and often lead to a divorce, it is better to have them early when you are still fresh and handle better the lack of sleep, divorce early and then enjoy part time parenthood when you are still youngish.
I feel I am a better parent now that I am sharing custody of my kids and can better balance personal life and hobbies and parenthood.
A cheaper option would be to find someone looking for kids with no romance and agree on having shared parenthood.
I had my kids late in life and I always thought my life experience was a bonus when it came to raising the kids and wrt keeping it together with the wife.
I’m vastly happier having had kids in my 30s rather than my 20s. Greater emotional and financial stability as well as a strong foundation for my marriage were boons.
Rather than accept divorce as an inevitability, there is also the option of discussing the possibility with your partner and making a mutual commitment to do what it takes to stay happy together.
Which is much easier with the added emotional maturity and life experience that comes with age.
Not to mention if you chose your partner after the age of 25.
