Anyone else a fan of the decade pregnancy? I'm talking about a woman who had kids in her 20s and 30s, stopped having kids, and just as the last kid starts to get older and not need her as much (when they're 10 years old or so - a decade), she decides to have one more baby right when she's in her early to mid 40s and can no longer have kids? Or she thought she couldn't have kids anymore and ended up getting knocked up?

They usually have a feel to them. For one, pregnancy is much harder now than when they remembered. They just look miserable being pregnant. Even moving seems hard to them. You might see them at the store and the only kid with her is clearly in middle or high school. They just do not give a fuck in like this largest expression of that domineering preggo mama energy you sometimes see.

If the pregnancy was by an accident, that almost mirrors the starting years of a woman's fertility. Just like how an accidental pregnancy can occur when you are young and not thinking or expecting to conceive, that same attitude is applied in similar context with the late "end of fertility window" pregnancy.

It's not that I like that the pregnancy is uncomfortable, I just love that sort of raw strength and beauty that comes with a woman choosing to go through something that hard at that stage of her life. Not saying that's too old to have kids, more that she made the decision to add another child after stopping for so long.

There are offshoots to it, of course. First time moms at 40+ fit that category, I'd say. It's just something I don't see talked about much. Hope at least some of that made sense haha.

All this of course assumes the ideals you would expect from this dreamt scenario: that the child will be loved, that the child is born healthy, that the mother will do right by the child, that the mother will love the child, that the mother wants the child, etc, etc blah blah

Geriatric pregnancy (35+) is definitely something a lot of folks here love the idea of. Back when Tumblr was still usable, I wrote several stories with it as a theme. I like your idea of a decade pregnancy - would be a really interesting idea to write about. I'm reminded of the final scene of Malcolm in the Middle when Lois reveals she's pregnant with their 6th kid despite the oldest 3 all graduated from high school (and Hal's reaction lol)

Some connected ideas I really like to imagine:
1. When a daughter and mother are both pregnant at the same time (double the accident!)
2. When an older woman serves as a surrogate for a younger family member or friend (gives off 'I did it once, I can do it again' vibes)
3. When an older woman who put off starting a family races the clock to use her remaining fertile years (pure determination despite her body not being what it used to be)

I had several similar stories around me like that (if I understand correctly what you say).

Some friends and neighbours had a daughter, then a child like 14 years later. It's weird to have children with such a difference of age but we're not here to talk about that.

I had differents scenarii. The first I remember was because they had their first daughter really soon, and wanted an other one at a most "classic" age. And an other had her children with her first husband, and the second with the following boyfriend. Like having a baby was a way to proof their love, or something like that
