What Is Breastfeeding Aversion and Who Does It Affect?

Breastfeeding aversion — sometimes called nursing aversion — is a real, recognized condition in which a mother feels intense negative emotions specifically during a feeding session. Pediatrician and breastfeeding specialist Dr. Lorene Mourão describes it as "a feeling of aversion to breastfeeding — an anguish, a desire to remove the baby from the breast, as if your body is being violated."

When Does Breastfeeding Aversion Typically Start?

Contrary to what many mothers expect, this condition rarely appears in the first months of a baby's life. It is most common from around 9 months onward, during extended breastfeeding, when the baby has greater awareness of the nursing act. It tends to intensify in specific situations:

  • When the menstrual cycle returns
  • During simultaneous breastfeeding and pregnancy (tandem nursing)
  • During late weaning or tandem breastfeeding
  • When the mother lacks an adequate support network

What Are the Symptoms to Watch For?

All symptoms appear exclusively during a feeding session and may include:

  • A strong urge to remove the baby from the breast
  • A feeling that the body is being violated
  • Anger or irritability during nursing
  • Agony, anguish or a sense of tightness
  • A desire to flee or end the feeding immediately
  • Chills or generalized physical discomfort
  • A feeling of revulsion toward the act of breastfeeding
  • Anxiety that grows as the baby approaches to nurse

Crucially, outside of feeding sessions the mother typically feels well and content with her child. This distinguishes nursing aversion from postpartum depression.

How Is Breastfeeding Aversion Different from D-MER?

Many mothers confuse nursing aversion with D-MER (Dysphoric Milk Ejection Reflex). They are different conditions. D-MER is directly linked to the oxytocin ejection reflex — some women with higher oxytocin levels experience dysphoria specifically at the moment of milk let-down. Breastfeeding aversion, by contrast, is broader and not tied solely to that reflex moment.

What Should You Do If You Recognize These Feelings?

The first step is knowing you are not alone and that this has a name. Seek support from a lactation specialist or pediatrician experienced in breastfeeding. Having a solid support network — whether family, friends or online communities — also plays a key protective role.

Key Facts:
  • Breastfeeding aversion is a real condition causing intense negative feelings during — but not outside — nursing sessions
  • Most common from 9 months onward, especially during extended or tandem breastfeeding
  • Triggers include the return of the menstrual cycle, concurrent pregnancy and lack of support
  • It differs from D-MER, which is linked specifically to the milk ejection reflex
  • Outside feeding sessions, mothers with this condition generally feel well and bonded with their baby
