How to Extract Infant Rigs for Posing?

As a pose creator, the thing I was most excited about with the infant life stage was being able to pose them! I want cute baby poses galore! But I can't seem to figure out how to access the infant rig to export it. I've tried opening up infant animations, infant clothes, anything I thought might have the infant rig in the blend file but no luck. Everything appears to be an adult rig for some reason?

Does anyone know how access and export the infant rig? Or if someone's already done it, could I get a link? TYIA!
