Anaparental: referring to a monopersonal/unipersonal family, wherefore a familial nucleus/entity consists of one person only.
Similar to unparental and soloparental, but this could be also autoparental (self-parenting). Reminder this is socioaffective/socioaffectional/socioaffectionate not biological.
Anglophones uses more -parenting than -parental(ity)/-parenthood apparently, I’m leaving here some keywords: anaparenting, uniparenting, autoparenting, unparenting/nonparenting, soloparenting, monoparenting, solopersonal, autopersonal, socioparenting, socioparental.
