I've seen a few people do this. They add a few bonuses through finished fanfictions for special holidays and such. That's what I'm thinking of doing. The child will be born and will be around a toddler, but I'm leaving the name up to you with (C/N) (child's name). They/them pronouns will also be used along with (C/S) (child's species) so they can be a human, hybrid, or skeleton!

The first bonus will start during summer (I usually have time to write more of these during summer).
