So far in my story, Lisa has given birth to and started taking care of her baby. This baby I know will be named Alma later on. But currently in my story, it has no name(not even a nickname). Gender has already been genetically predetermined but externally, it doesn't show until the child's 5th birthday. Right now the baby is 2 weeks old and getting some climbing practice(Lisa's species is fast developing in physical and social milestones but slow in transition from breastmilk to solids). I don't know how to refer to an unnamed baby with unknown gender without implying a certain gender or using "it". I know "he" is used a lot for unknown gender but that implies male. "He/She" is used a lot but again it implies male or female(and not all creatures have males and females, some have other genders and some are genderless). The only other one I can think of to use is "it". But several people have told me that that means the baby is an object, not a character. "They" implies plural(which if this were twins or above I would use but this is a singleton) and the Xis/Xe/Xir etc. are just too odd for me. How else can I refer to the character without using any of these or "that baby" or "the baby"?
