As the BBC commentators have just said, most of the medals that have gone to the Netherlands seem to have come from either Sifan Hassan or Femke Bol, their great hurdler/400m runner. She's only 24. There could be a lot more to come from her too.
Fanny Blankers-Koen (NL) took 3 individual medals in the 1948 Olympic games (could have been more). NL seems good at individuals winning multiple medals in women's athletics. FBK did that after a 12 year-gap (WWII) and children. I can't find it but there's a famous photograph of her training with her young children playing in the long jump like it's a sandpit.
As the world record holder in both the high jump and long jump at the time, it’s possible she could have added two more gold medals in 1948, but Olympic rules allowed participation in only three individual events, and the Dutchwoman chose to run rather than jump.

In her first competition, Blankers-Koen led the 100-meter dash nearly from start to finish.
In her next event, she had to work the hardest, coming from behind to barely win the 80-meter hurdles, but still in Olympic record time.
In her third triumph, Blankers-Koen won the 200-meters in the first lane, eating up the water-drenched track like a locomotive, well ahead of the 2nd place finisher, in Olympic record time.
And finally, in 4×100 meter relay, the Dutch team, in their orange shorts, were trailing in third when their anchor, Blankers-Koen took the baton. And like a rocket, she shot to the lead and crossed the line with her fourth gold medal.
