Earlier quoted context omitted.
The upside is that I was a total basket case in my 20s, completely incompetent to be able to raise a child. I'll leave it to my children on how it turned out in my 30s. Generally I'd expect older adults to have done a lot more maturing and increased ability to emotionally regulate, which is a really critical ability when dealing with the 4th day of 3 hours of sleep and a colicky baby (for example). Also no point. But…
Interesting how until recently people in their early 20s were perfectly capable of raising children, but today they’re not.
I don’t think it’s a bad thing (why not spend your 20s exploring?) but it’s also easily explained by financial burdens that didn’t used to exist. Housing is now very expensive, can you blame people waiting until they have the right size home before they have kids?
