I think there's a lot to be said for getting married a bit younger/having babies younger. I don't mean 16, but like early to mid 20s. Only if you have found the right person of course, and not get married for the sake of it.
I know half a dozen or so women who got married at 19-23, (some 20 to 25 years ago,) and had a child within 2 years. They are now mid 40s, and their children are married with one or two kids now. (Got married within the past 3 to 8 years or so) The 40-something parents are able to help their young adult children, as they have all the energy and good health to help with life in general. Financially, with the grandkids, and with general grunt work.
I know a number of families where the young mums and their little children/babies/toddlers have great support from middle aged grandparents. And they still have the great grandparents alive. There's a great support network around them. And younger people manage finances the same as older people. They work! And many younger people (in their 20s,) who I know, earn a lot more than people a generation older.
There's not the same network when you have babies much later (40+) IMO and in the experience of some people I know.
When you don't get married/have kids til say, your very late 30s/early to mid 40s, your parents are very likely going to be quite elderly and unable to help as they could have - if you had had children 15-20 years earlier.
And you yourself (at 45-ish with a small child) are going to struggle too, with tiredness and exhaustion, and by the time they're teens you'll be in your 60s. And you will find it a real struggle looking after young tweens and teens at a point in your life where your kids should have left home a decade ago.
And I know a bunch of posters will come on and say their 75 year old mother is a vibrant firecracker with more energy than a thousand condensed suns, and they themselves at 50, run 10 marathons a year and could run rings around women half their age, but the fact is that the health (and energy levels) of most people, starts to wane when they hit 48-50 or so. And the energy levels, (and often health too,) start diminishing a lot more by mid 50s. NEVER under-estimate the effect the menopause will have on you.
Being a mother of young boisterous children in your late 50s/early 60s is not something anyone should be aspiring to IMO. In addition, as I said, if you're waiting til mid 40s to have your kids, your own parents are very unlikely to be of any support, as they will very likely be 70+ themselves by then. And the fact is that most people that age will not want to look after little kids. Some won't even be capable of it.
JMHO.
