The term “chestfeeding” was created as a gender-inclusive alternative to “breastfeeding,” primarily for transgender men and non-binary parents who experience distress when their bodies and parenting roles are described with female-associated language. While the physical process is the same, the word “breast” carries strongly feminine connotations that can conflict with how some parents understand their own gender. “Chestfeeding” reframes the act around a more neutral body part, the chest, without changing what’s actually happening: feeding a baby with human milk.
The Problem With Gendered Language
For most parents, the word “breastfeeding” is perfectly comfortable. But for transmasculine individuals, those assigned female at birth who identify as male or non-binary, being called “mom” or told to “breastfeed” can intensify a condition called gender dysphoria. That’s the significant psychological distress that arises when the way other people describe you doesn’t match your gender identity. A qualitative study published in BMC Pregnancy and Childbirth found that words like “she,” “mother,” “breasts,” and “breastfeeding” could be deeply distressing for parents who don’t identify that way, and that healthcare providers sometimes cause harm without realizing it simply by defaulting to this language.
The word “breast” is anatomically accurate regardless of sex. But as lactation researcher Laura Dinour has noted, the term has been so thoroughly gendered in everyday use that it carries a negative connotation for transmasculine individuals, many of whom already refer to that area of their body as their “chest.” Swapping one word removes a source of repeated discomfort during an already vulnerable time.
Who Uses the Term
Chestfeeding is used mainly by transgender men and non-binary parents, along with the healthcare providers who support them. It’s not intended to replace “breastfeeding” for everyone. Most lactation resources now treat both words as valid options, with the choice left to the individual parent. Some people also use “bodyfeeding,” “nursing,” or simply “feeding” as neutral alternatives.
The distinction matters most in clinical settings. When a new parent is already navigating hormonal changes, sleep deprivation, and the physical demands of feeding an infant, being repeatedly misgendered by a nurse or lactation consultant adds a layer of stress that can undermine the whole experience. Asking a patient which term they prefer takes seconds and costs nothing.
Medical Organizations That Recognize It
The term has moved well beyond informal use. The Academy of Breastfeeding Medicine, a leading professional organization, published an official position statement on lactation-related language and gender. Their guidelines recommend “desexed or gender-inclusive language” in written materials, such as “lactating person” instead of “mother.” Their suggested terminology table lists “chestfeeding” alongside “breastfeeding,” “lactating,” “expressing,” and “human milk feeding” as gender-inclusive options.
The UK’s National Health Service has a dedicated page titled “Chestfeeding if you’re trans or non-binary,” which defines chestfeeding as “feeding your baby with your own milk produced by your chest.” This signals that major public health systems consider the term clinically legitimate, not just a social preference.
How Chest Surgery Affects Lactation
One reason the term “chestfeeding” exists as a distinct concept, not just a synonym, is that many transmasculine parents have undergone chest masculinization surgery (commonly called top surgery). This changes the practical reality of feeding in ways that don’t apply to most breastfeeding parents.
Unlike mastectomy for breast cancer, chest masculinization often retains some breast tissue because the goal is a natural-looking masculine chest contour rather than complete tissue removal. Whether someone can still produce and deliver milk afterward depends heavily on the surgical technique used. Research on breast reduction surgery shows that when the nipple stays connected to the underlying glandular tissue, some milk production and removal capacity can survive. But the most common masculinization technique involves separating the nipple from the tissue underneath and grafting it back on in a new position. When the nipple has been fully detached and reattached this way, milk removal through the nipple is essentially impossible, even if glandular tissue remains.
Nipple reduction, a common add-on procedure, can also eliminate the functional openings through which milk would exit. Surgical complications like tissue death can result in partial or complete nipple loss. Taken together, these factors mean that many people who have had chest masculinization surgery will not be able to both produce and extract milk. In documented cases, the few individuals who had some success had undergone techniques that kept the nipple connected to underlying tissue. Those who had nipple grafts were generally unable to produce milk, and some who retained breast tissue but lacked a functional nipple experienced painful engorgement with no way to relieve it.
For those who want to feed at the chest despite surgical limitations, supplemental nursing systems (a thin tube taped near the nipple that delivers formula or donor milk while the baby latches) are sometimes an option. But reduced breast tissue can make latching difficult, and grafted nipples may have poor sensation and fragile blood supply, making them vulnerable to damage.
Why the Terminology Debate Persists
The word “chestfeeding” is straightforward in intent: give people a term that doesn’t cause them distress. The debate around it tends to focus on whether gendered language should be changed at all, or whether inclusive terms might dilute health messaging aimed at the vast majority of lactating parents who are cisgender women. Most major medical bodies have settled on a both/and approach: use “breastfeeding” as the default in general contexts, and offer “chestfeeding” or other neutral language when working with patients who prefer it.
This mirrors broader shifts in clinical communication. Research consistently shows that patients engage more openly with providers who use their preferred language, whether that’s about gender, culture, or simply which terms feel familiar. Tailoring language to the person in front of you isn’t about rewriting biology. It’s about removing a barrier between a parent and the support they need to feed their baby.
