Mastitis is a common concern among breastfeeding moms and can bring a lot of discomfort if it arises. But don’t worry—knowing what mastitis is, why it happens, and how to prevent and manage it can make all the difference. In this post, we’ll explore the causes of mastitis, steps to prevent it, and what to do if you start experiencing symptoms.
What is Mastitis?
Mastitis is an inflammation of the breast tissue that can lead to infection if not managed promptly. It typically occurs when milk becomes trapped in the breast, leading to a blockage and, potentially, bacterial growth. Mastitis can cause pain, swelling, warmth, and redness in the affected area, and it may also bring on flu-like symptoms such as fever, chills, and fatigue.
While it’s most common in the first few weeks of breastfeeding, mastitis can develop at any point, so staying informed about it is essential for all breastfeeding moms.
Common Causes of Mastitis
Several factors can contribute to the development of mastitis, including:
-
Engorged Breasts: When milk builds up in the breast without being expressed, it can lead to painful engorgement, making it more challenging for milk to flow freely and potentially causing blockages.
-
Clogged Milk Ducts: If a duct becomes blocked, milk can get backed up in the breast, increasing the risk of infection.
-
Poor Latch or Feeding Position: An improper latch can mean milk isn’t emptied from the breast effectively, leaving milk to accumulate.
-
Sudden Changes in Feeding Schedule: Skipping feeds or reducing nursing frequency too quickly can cause milk to pool, which can lead to mastitis.
-
Pressure on the Breasts: Tight bras, sleeping on your stomach, or carrying heavy bags across your chest can all put pressure on the breast, potentially leading to a blocked duct.
Tips for Preventing Mastitis
Thankfully, there are several proactive steps you can take to reduce the risk of mastitis while keeping breastfeeding a smooth and enjoyable experience:
-
Ensure a Proper Latch
- Working with a lactation consultant to perfect your baby’s latch can help ensure milk flows properly, reducing the likelihood of milk stasis and blockages.
-
Frequent and Consistent Feeding
- Regular feeding or pumping helps keep milk moving and prevents it from building up in the breast. Try to stick to a consistent schedule, especially if you’re experiencing fullness or engorgement.
-
Alternate Feeding Positions
- Changing up positions can help different areas of the breast drain more effectively. The football hold, cradle, and side-lying positions are all useful options to keep milk flowing.
-
Stay Hydrated and Well-Nourished
- Hydration and good nutrition support milk production and your immune system, helping your body stay resilient.
-
Wear Comfortable, Non-Restrictive Clothing
- Choose loose, supportive bras that don’t compress the breast. Tight clothing can restrict milk flow, so it’s best to avoid it while breastfeeding.
-
Massage During Feeding
- Massaging the breast, especially areas that feel firm, can encourage milk flow and prevent blockages. Be gentle, and try focusing on areas that might feel tender or engorged.
-
Consider Moogco Silver Nursing Cups for Comfort
- Moogco Silver Nursing Cups can be helpful for preventing nipple pain or soreness. They provide a natural barrier between your nipple and clothing, which can reduce irritation and make breastfeeding more comfortable—encouraging regular, uninterrupted feeds that help reduce the risk of mastitis.
Recognizing Mastitis Symptoms
Sometimes, despite your best efforts, mastitis can still occur. Symptoms of mastitis include:
- Swollen, red, or warm areas on the breast
- Pain or tenderness in one or both breasts
- Fever and chills
- Fatigue or general feeling of unwellness
- Achy or flu-like symptoms
If you notice any of these symptoms, it’s essential to act quickly. Early intervention can prevent the condition from worsening.
Managing Mastitis
If you’re experiencing symptoms of mastitis, try these steps:
-
Continue Nursing or Pumping: While it may be uncomfortable, emptying your breast is essential. This helps to relieve engorgement and flush out any potential blockages. Start with the affected breast if possible.
-
Apply Warm Compresses: Before feeding, use a warm washcloth or a gentle heat pack on the affected area to help with milk flow and reduce discomfort.
-
Massage the Area Gently: While nursing, use gentle circular motions on the swollen area to encourage milk movement and help break up blockages.
-
Rest and Stay Hydrated: Your body needs extra support, so make sure you’re resting as much as possible and drinking plenty of water.
-
Over-the-Counter Pain Relief: If needed, speak with your healthcare provider about safe pain relievers to help manage discomfort.
If symptoms persist for more than 24 hours or if they worsen, reach out to a healthcare provider. They may prescribe antibiotics if there’s an infection, so you can recover and continue your breastfeeding journey comfortably.

Can I still breastfeed on the affected breast if I have mastitis?
Yes, absolutely. Continuing to breastfeed on the affected breast is actually one of the most important steps in treating mastitis. Emptying the breast helps clear the blockage and prevents milk from building up further. Your milk is safe for your baby, even if you have an infection.
How long does it typically take for mastitis symptoms to improve?
With proper treatment, including frequent nursing and rest, you should start feeling better within 24 to 48 hours. If your symptoms don't improve after 24 hours or if they get worse, contact your healthcare provider right away. You may need antibiotics to clear the infection and prevent complications.

Is mastitis contagious to my baby or other family members?
No, mastitis itself is not contagious. It's an inflammation or infection inside your breast tissue, not something that spreads to others. Your baby can continue nursing safely, and you don't need to worry about passing it to family members through normal contact.
Can mastitis come back after I've had it once?
Yes, some moms do experience recurrent mastitis, especially if underlying issues like poor latch or infrequent feeding aren't addressed. Focusing on prevention strategies like proper latch, regular nursing schedules, and avoiding tight clothing can significantly reduce your risk of it happening again.
What's the difference between a clogged duct and mastitis?
A clogged duct is a localized blockage that causes a tender lump in one area of the breast, but you generally feel fine otherwise. Mastitis includes inflammation or infection and often brings flu-like symptoms such as fever, chills, and body aches. A clogged duct can progress to mastitis if not resolved quickly.
Should I pump or hand express if nursing is too painful during mastitis?
If nursing is too uncomfortable, pumping or hand expressing is a great alternative to keep your breast emptied. The key is to remove milk regularly to relieve pressure and clear the blockage. Try starting with warm compresses and gentle massage before expressing to help milk flow more easily.
Can stress or lack of sleep contribute to developing mastitis?
Yes, both stress and exhaustion can weaken your immune system, making you more vulnerable to infections like mastitis. When you're run down, your body has a harder time fighting off bacteria. Prioritizing rest, staying hydrated, and asking for help when needed are all important for prevention.
Do I need to stop breastfeeding if I'm prescribed antibiotics for mastitis?
No, most antibiotics prescribed for mastitis are safe to take while breastfeeding. Your doctor will choose a medication that won't harm your baby. In fact, continuing to nurse helps you recover faster by keeping milk flowing and preventing further blockages.
