Each breastfeeding journey is unique and extraordinary. Breastfeeding impacts women mentally and physically and offers a variety of health benefits for mothers. In this blog, we will focus on the mental health benefits of breastfeeding. Scientific evidence shows that breastfeeding has a positive impact on postpartum mental health. Let’s dive into how breastfeeding impacts mental health and the amazing science behind it all.
Hormonal Support for Mood:
Oxytocin and prolactin are beneficial hormones for breastfeeding mothers. Let’s dig into how these hormones support a better overall mood.
Oxytocin – The “Love Hormone”
- Released during letdown: When a baby suckles, the brain triggers the release of oxytocin from the pituitary gland. This is the letdown reflex that encourages the milk to flow, but also has psychological effects.
- Promotes bonding: Oxytocin enhances feelings of love, connection, and emotional bonding with the baby.
- Reduces stress and anxiety: Oxytocin lowers cortisol levels (the stress hormone), creating a sense of relaxation and well-being.
- Improves sleep: Oxytocin can promote deeper, more restful sleep.
Prolactin – The “Mothering Hormone”
- Supports milk production: Prolactin levels rise in response to nursing to help maintain milk supply.
- Encourages calmness: It contributes to a nurturing, “mothering” state that makes mothers more responsive and attentive to their babies.
- Helps emotional regulation: Prolactin is linked with a sense of satisfaction and contentment, which can help buffer against mood swings.
Brain Chemistry and Mood
Breastfeeding increases levels of dopamine and serotonin, neurotransmitters linked to mood regulation. These chemicals help create a reward loop in the brain, reinforcing positive feelings and a sense of achievement.
When Breastfeeding Contributes to Mental Health Struggles
Breastfeeding can come with many challenges and struggles. Some of the things that can hurt your mental health while breastfeeding include:
- Societal and cultural pressures may discourage breastfeeding.
- Pain, latch issues, or low milk supply can create stress, anxiety, and sadness.
- Recurrent breastfeeding issues can trigger post partum depression (PPD).
- Difficulty breastfeeding may exacerbate mental illness, and vice versa.
Consider that what feels difficult and overwhelming today might be easier tomorrow. Just because you feel the motherhood weight today does not mean that tomorrow you won’t feel better. Take things one day at a time and celebrate the small wins.
Emotional Support During Breastfeeding
It is important to establish a solid support system before birth to have throughout your breastfeeding journey. Mothers should be expressive of goals and discuss boundaries with their spouse, close family members, and friends surrounding breastfeeding. These support systems will be those who help with you prioritizing sleep and nourishment during your postpartum journey.
Establishing care with a trusted IBCLC is also a great idea.
Establishing care with a professional will likely reduce the chance of negative outcomes discussed in the section above. Even if you don’t have complications, having an expert on board helps you feel reassured during the normal stages of breastfeeding.
Another great tool mothers have is social media, there are hundreds of breastfeeding support groups online for mothers to share their experiences and support one another through their journeys, cheering on one another’s success. But be careful navigating these as well because they might have some misinformation about breastfeeding.
You may find it helpful to seek mental health support groups in your area as well. There are also many online options!
Key Research Findings
1. Exclusive Breastfeeding and PPD Risk
A systematic review and meta-analysis published in the Journal of Affective Disorders found that women who did not exclusively breastfeed had significantly higher odds of developing PPD. Specifically, non-exclusive breastfeeding was associated with an 89% increase in the odds of PPD (Odds Ratio [OR] = 1.89, 95% Confidence Interval [CI]: 1.50–2.39) compared to exclusive breastfeeding.

2. Current Breastfeeding Status and Depression
A large-scale study conducted by Florida Atlantic University analyzed data from 29,685 women across 26 U.S. states. The study found that women who were currently breastfeeding at the time of data collection had a statistically significant lower risk of postpartum depression compared to those who were not breastfeeding. Additionally, the study observed an inverse relationship between the duration of breastfeeding and the risk of PPD; as the number of weeks of breastfeeding increased, the risk of PPD decreased.

3. Intent to Breastfeed and Mental Health Outcomes
Research published in the Maternal and Child Health Journal indicated that mothers who planned to breastfeed and subsequently did so were approximately 50% less likely to experience postpartum depression than mothers who intended to breastfeed but did not. This finding underscores the importance of aligning breastfeeding intentions with actual practices in relation to maternal mental health. La Leche League GB

Nurturing Body, Mind, and Baby through Breastfeeding
Breastfeeding can be a powerful contributor to a mother’s emotional well-being. The natural release of calming hormones, the deepened connection with your baby, and the sense of purpose and accomplishment from nursing all contribute to better mental health and overall wellness.
While the journey isn’t always easy, many women find that overcoming early challenges and finding their rhythm with breastfeeding brings a renewed sense of confidence, resilience, and joy. It’s more than just nourishment—it’s a unique bond that can uplift both mother and child.
If you’re on this path, know that support, education, and encouragement can make a world of difference. Surround yourself with people who empower you, seek guidance when needed, and celebrate your wins, big or small.
