Adult Nursing Relationship (ANR) – Excerpt
The suckling of milk from a female’s breast on a regular basis from one or more partner(s). Successful ANRs depend on a stable and long-term relationship, as otherwise it is very difficult to maintain a steady milk flow. 
Couples may begin an ANR by transferring regular suckling from a child to a sexual partner (e.g. spouse). Such a relationship may form as an expression of close intimacy and mutual tenderness, and may even exist without sex. Breastfeeding can have a strong stabilizing effect on the partnership. The breastfeeding woman may experience orgasms or a pleasurable let-down reflex.
ANRs have also been employed in cases where a mother may desire to breastfeed her child, but has to find an alternative to inducing lactation. She may have difficulty beginning lactation, so she supplements the infant’s suckling with that of a partner. Or there are cases where breastfeeding was interrupted for an extended period of time as a result of infant prematurity, infant absence, or mother’s illness (taking prescription medication). In such cases, adult nursing has often caused lactation to continue until it was possible for the child to resume breastfeeding. Others may want to nurse an adopted child, so use an ANR to stimulate breast milk production before the adoption occurs. Though such scenarios do not have erotic motivations, erotic expression may be an additional aspect of the relationship.
