I don't know if the game thinks Lalas are children or not. Sometimes they are treated like adults, with specific characters & having jobs, but the emotes and tooltips like the high chair say otherwise. I'm more confused about that aspect. Keep in mind that this is the game that changed the name of "beast tribes" because that is hurtful to npcs. Maybe they should decide what a Lalachild and a Lalaadult actually are.

I personally wouldn't mind either way. Being a cute potatoe :3
