Transgender and Non-Binary Nursing

LLL USA supports everyone in reaching their breastfeeding, chestfeeding, and human milk-feeding goals. Para información en Español

Trans men, trans women, and non-binary individuals may choose to breastfeed or chestfeed their babies. You do not need to have given birth to breastfeed or chestfeed, as we can also see in the experiences of those nursing adopted babies.

LLL Canada Leader and transgender dad Trevor MacDonald writes that, “It is equally important to note that some trans people experience severe gender dysphoria when breast or chestfeeding, and that they may decide not to nurse their babies for mental health reasons. Trans parents choosing to breast or chestfeed and those choosing to suppress lactation and bottlefeed may require the support of breastfeeding counsellors or lactation professionals.”   It is also the case that some parents with gender dysphoria choose to pump and bottlefeed their milk to their baby. Whether you are pregnant, nursing your baby, pumping your milk, using donor milk, mixed feeding or considering your options La Leche League is here for you.

Human milk is amazing. It has everything a growing baby needs in exactly the right amounts. Plus, babies can easily digest it all. Research shows that a baby who is not fed on human milk is more likely to suffer from illnesses and diseases, both as a child and later in life.
By meeting your baby’s needs for warmth, food, and security at your chest you give them a secure attachment so they can develop into a confident child.


Skin-to-skin contact is beneficial for babies and parents; it simply means holding your naked baby on your bare chest. You can drape a blanket over you both for warmth. Within minutes, you will see the benefits of skin-to-skin as you and your baby relax. Your baby’s body temperature, breathing, and heart rate will stabilize. Babies often latch on and nurse more efficiently during and after skin-to-skin contact.

It is a lovely way to nurture your baby even if you are not nursing.


Some transgender and non-binary parents have a full milk supply.

If you have had chest (top) surgery you may be able to produce some milk. Many factors will affect the amount of milk you can make.

Two reasons that a trans man or non-binary individual might have a reduced milk supply are:

  1. Milk-making tissue has been surgically removed, and/or ducts have been damaged in surgery.
  2. Testosterone interferes with the hormone necessary for lactation (prolactin) and can cause a significant decrease in milk supply. However, taking testosterone would not prevent someone from using an at-chest supplementer and having a nursing relationship.

Trans women can use a protocol similar to adoptive and other non-gestational parents and stimulate their milk supply: it is called the Newman-Goldfarb protocol. You can read more here. Transfeminine nursing parents may also need to take the hormone spironolactone to suppress their testosterone.

You can also give human milk or formula supplements using an at-breast supplementer. Your healthcare provider can help you look at your options, and your local LLL Leader can offer support with your breast or chestfeeding goals and journey.

You may find the following websites have useful information, you may notice gendered language in them:

Many parents worry about whether their baby is ‘getting enough’. LLL meetings are a good place to get support from others.

Be sure to check the Is my Baby Getting Enough Milk? to ensure baby is feeding effectively.


If your baby needs a supplement of expressed milk or formula you might want to consider using a nursing supplementer. Doing this can give your baby that extra milk while they are nursing.
Supplementers can help parents have an at-breast or at-chest relationship with their baby whether or not they are able to produce milk. Supplementer may also be called by the brandnames Supplemental Nursing System (SNS) or Lact-Aid Nursing Training System. There are also many low cost, do-it-yourself options that are just as effective.

Some transgender and non-binary parents use milk banks to acquire human milk for their babies. LLL USA fully supports the use of human milk for babies; we cannot facilitate or set up milk sharing networks, though your local LLL Leader can help you with contact information for non-profit human milk banks, other regulated collection centers, and peer-to-peer milk sharing networks.
