A ton of girls I graduated high school with married successful guys in their 40s right away and started having kids. They weren’t in different phases in life with their husbands though, they were all just ready to settle down and raise kids. It seemed weird to me at the time but it makes sense to me now, they just didn’t want to bother with dating college guys to see if it turned into having children 10 years later, they were ready to go and found partners with the same plan.

I just couldn’t imagine raising my children with a 50-60yr old, as a 20-30yr old 

Also doesn’t sperm quality decrease as men age, leading to more defects in children?
