Since a lot of people are enjoying the idea of Cross children, allow me to dump a few little ideas:
Different AMs using different kinds of alien technology to start making ridiculous (and sometimes dangerous) children's toys
Xeno tech being something kids see as "normal"
Other Crosses babysitting
Other Crosses setting up playdates for whole groups of kids
Playgrounds all over NLA
Plush versions of the indigens of Mira being given to babies
Hope setting up a school for all the kids
Skell booster seats
Badass grandpa Nagi
Kids playing games like 'BLADES and Ganglion' and 'Find the Core'
Domesticating smaller indigens as pets
Junior BLADE training
Whole groups of kids having nighttime camping in Primordia under the Meteor Showers
Everyone in BLADE trying their best to give these kids a proper, happy childhood on this hostile alien planet
