Adult Baby / Diaper Lover

Autonepiophilia: popularly known through the community acronym ABDL (adult baby / diaper lover): is an interest in perceiving, presenting or being treated as a baby or toddler. The "adult baby" strand centres on infantile role-play and being nurtured; the "diaper lover" strand centres on the diaper itself as a comfort or erotic object. The defining theme is voluntary age regression to early childhood as a role or identity. It must not be confused with sexual interest in actual children, which is an entirely separate, harmful and illegal phenomenon: pedophilia runs in the opposite direction, since ABDL adults imagine themselves as infants rather than being attracted to them. For many adherents the experience is rooted in comfort, safety and stress relief as much as, or more than, sexuality.

Examples

What the term covers. Everyone involved is an adult. In its diaper-focused form, an adult wears a diaper privately or with a partner for the feel, bulk and containment of the garment and the calm it produces. In its adult-baby form, an adult adopts an infant or toddler persona, with soft clothing, a pacifier, a bottle or a nursery-styled room, often with a consenting partner taking a caregiver or "Mommy/Daddy" role, and frequently with no erotic content at all: many participants describe littlespace as an emotional refuge from adult pressure rather than as sex. Most of it is private, most of the community life is online, and the two strands mix freely in the same person.

What the term does not cover. It has nothing whatever to do with children. ABDL is an adult imagining themselves as an infant; pedophilia and nepiophilia are sexual attraction to real children and real infants, are harmful and illegal, and are the opposite direction of interest rather than a milder version of it. No minor is involved in any recognised form of this practice, and the community polices that boundary explicitly. Among the adjacent adult interests, age-play is the wider umbrella of enacted age difference and need not involve infancy at all, DD/lg names a caregiver-and-little relationship dynamic, diaper fetish is the garment interest standing on its own, and omorashi concerns the sensation of desperation and wetting rather than the diaper or the role.

How the word is used. "ABDL" is community vernacular, assembled online and now the standard self-description. The clinical labels are autonepiophilia and paraphilic infantilism, and they are descriptive rather than diagnostic: neither DSM-5-TR nor ICD-11 lists infantilism as a disorder in its own right. "Adult baby syndrome" is narrower still, a label from a 2003 case report reserved for rare, impairing presentations rather than for the community at large.

History & origins

Clinical lineage

The idea of an adult eroticising the role of an infant was foreshadowed in the founding catalogues of sexology, Richard von Krafft-Ebing's Psychopathia Sexualis (1886) and Havelock Ellis's Studies in the Psychology of Sex described unusual erotic patterns and supplied the descriptive groundwork, though neither named this specific interest.

• 1986: The American sexologist John Money, who built much of the modern paraphilia vocabulary, set out a family of age-impersonation paraphilias in Lovemaps (1986) and coined the reciprocal term nepiophilia (from Greek nepios, "infant") for sexual attraction to actual infants: a harmful condition that is the opposite of, and unrelated to, autonepiophilia.
• 1984: According to the Wikipedia account of paraphilic infantilism, Money coined autonepiophilia itself (Greek autos ("self") + nepios ("infant") + -philia ("love"), literally "love of oneself as an infant") for the desire to impersonate and be treated as a baby, with no attraction to children.
• 2003: Psychiatrists Jennifer Pate and Glen Gabbard published "Adult Baby Syndrome" in the American Journal of Psychiatry (160:11, 1932–1936), a clinical case conference on an extreme presentation; the label adult baby syndrome is reserved for such rare, impairing cases rather than the benign community at large.
• 2014: Kaitlyn Hawkinson and Brian Zamboni's exploratory survey of 1,795 male and 139 female ABDL members in Archives of Sexual Behavior (43:5, 863–877) examined mood, parental relationships and attachment, and identified two overlapping subgroups: people centred on role-play and people centred on the diaper as an object of arousal, confirming that the "AB" and "DL" strands are distinct but linked.

Modern clinical literature folds the interest under paraphilic infantilism. Like other paraphilias in the DSM-5-TR and ICD-11, it is not a disorder in itself; it becomes a diagnosable paraphilic disorder only when it causes the person marked distress or impairment, or involves harm to others.

Cultural & subcultural evolution

The acronym AB/DL and its "adult baby" and "diaper lover" branches are products of the internet era; their precise origins are, as Wikipedia notes, "difficult to determine." Usenet groups, dedicated forums and later FetLife let geographically dispersed individuals find one another and articulate a shared identity distinct from the clinical framing: often emphasising littlespace, caregiving and comfort over pathology. The community overlaps with, but is not identical to, age-play and DD/lg dynamics, and its signature object connects it to the standalone diaper fetish.

In practice

Expression is typically private and role-based, and is highly individual:

• role-play and props associated with infancy or toddlerhood;
• soft, nurturing routines of being cared for, sometimes with a partner in a "caregiver" or "Mommy/Daddy" role;
• for the diaper-lover strand, a focus on the garment itself as a comfort or arousal object;
• an overarching emphasis on comfort, escape and self-soothing.

The Hawkinson–Zamboni subgroups capture the spread: for some the interest is primarily a regressive, emotional refuge, and for others it is more overtly erotic, and the two often coexist in the same person.

Psychology

Proposed accounts emphasise regression as a route to relaxation, escape from adult pressures and a sense of being unconditionally cared for; these themes are frequently linked to attachment and self-soothing. Some researchers have explored "erotic target identity inversion", desiring to be the thing one is drawn to, as one framework for the role-play strand; Hsu and Bailey (2023) reported a pattern consistent with this idea in a male ABDL sample, while noting that the evidence base remains small and contested, drawn largely from self-selected online samples. There is no good evidence that ABDL interests stem from abuse or signal a risk to children; surveys describe a largely well-adjusted, predominantly male population (in the 2014 study about 93% of participants were male).

Prevalence & culture

ABDL interests are uncommon but sustain large, well-organised online communities and draw periodic mainstream-media attention. Rigorous population prevalence figures are scarce, research has concentrated on the psychology of self-selected community samples rather than on incidence, so any single percentage should be read as indicative rather than definitive. The most cited modern data point is the size and activity of online communities such as FetLife groups, which serve as a community-size proxy for a niche but durable interest.

Safety, consent & law

Among consenting adults the interest is legal and, practised privately, harmless; practical considerations are ordinary ones: hygiene, honest communication and clear consent, with aftercare valuable when regression is emotionally intense. Crucially, autonepiophilia concerns adults exclusively and must never, in any form, involve actual minors; that boundary is what separates it categorically from the harmful conditions Money named alongside it.
