HEYO! It's Flutterchord! Who coulda guessed?
Actually, it's still a friendship here! In this Next Gen, Discord and Flutters are ace pals!
So how do they end up having kids!
Well…

Eventually, they decided to have kids as most couples do. Though, there was a lot of concern. Mainly is a pony could handle a chaotic being in their body. But Flutters was insistent, and eventually Discord agreed to use his magic to impregnate Flutters.
Unfortunately, pretty much everything went wrong. Turns out, the concern for Flutters wellbeing was correct, and she ended up having a rough pregenancy, ending up in nearly dying in childbirth. She turned out fine, but they both decided that it would be best not to have anymore children.
But at least they have their kid…s?
