Breastfeeding aversion while pregnant is not uncommon, but it’s certainly not commonly discussed. Hormonal changes and sensitivities absolutely affect how a breastfeeding mother experiences nursing

• Hormonal Shifts: Increases in hormones, especially progesterone, can influence sensory experiences. This may contribute to heightened sensitivity or discomfort in the nipples and breasts from anatomical changes that happen during pregnancy to prepare for new baby
• Changes in Milk Composition: As your body prepares for new baby, breast milk shifts back to colostrum, usually by the end of the first trimester. Colostrum is thicker, saltier, and flows slower than mature milk which may change how an older nursling sucks at the breast, heightening sensitivities
• Nursing Aversion and Pregnancy: Nursing aversion or agitation during pregnancy is where a mother experiences discomfort, irritation, or negative feelings while breastfeeding. It's thought to be related to hormonal fluctuations and changes in nipple sensitivity. I’ve interviewed many mothers who report that, only while they are latched, they have violent thoughts related to the nursling for how intense they experience these negative feelings and sensations 
• Emotional Factors: Pregnancy itself can bring a range of emotions and physical discomfort. Stress, fatigue, or concerns about the upcoming birth and new baby can contribute to feelings of aversion during breastfeeding

If you're experiencing breastfeeding aversion while pregnant and find it challenging, know you are not alone and this is a very common experience 

• Communication: Openly communicate with your partner and healthcare provider about your feelings. Sharing your experience can provide support and understanding.
• Self-Care: Prioritize self-care to manage stress and fatigue. Ensure you're getting adequate rest, staying hydrated, and engaging in activities that bring you comfort.
• Alternative Feeding Options: If breastfeeding becomes too uncomfortable, explore alternative feeding options such as expressing milk or gradually introducing other sources of nutrition.

It's crucial to seek guidance from your healthcare provider or a lactation consultant for personalized advice based on your specific situation. They can offer support, address concerns, and help you make informed decisions about breastfeeding during pregnancy.
