I felt like doing some worldbuilding, so here’s an Atlacatl couple with their small children! These two are monogamous, but polygamy is just as acceptable in their culture, and their people don’t really do marriage.

Lore:

Real-world axolotls lay hundreds of eggs at a time. The Atlacatl don’t go quite as hard, but one clutch of eggs can still number in the dozens. Of these, usually only half or so will hatch, but it still goes without saying that these people take family planning very seriously.

The new babies are small, completely aquatic, and precocial. Still, raising so many children is a big task, and it’s shared by the whole community. Everyone helps guide the children through important milestones, such as teaching them to walk once their legs grow in.

With how quickly families can grow, it’s common for just a handful of families to make up a whole village. Inter-village fairs and dances are held to help people meet new faces, since pairing up with one’s first cousins is considered kind of tacky.
