You have a complicated issue. If your kids are humanoid, I think they still have authority, particularly if they are at least 50.1% human. If you treat other species as your kids I think you're mostly fine. For example, if your pet dog, cat, fish, reptile, anphibian, chicken or other bird are your children, your're fine - especially if you provide home study. However, I noted you use the term kid. Kids (whether human or goat) are required to be schooled.
