Lanolin is a highly purified, medical-grade substance derived from sheep’s wool, recommended for mothers experiencing initial discomfort while nursing. This natural, waxy material is processed extensively to remove impurities, making it safe for both mother and infant. Its primary function is to act as an occlusive moisturizer, creating a protective barrier that soothes and helps heal dry or cracked nipples. By trapping existing moisture, lanolin supports the natural healing process and reduces friction during and between feedings.
Proper Application for Initial Soreness
The correct technique for applying lanolin is important for maximizing its protective and soothing benefits. Begin by warming a pea-sized amount of the ointment between clean fingers to soften its texture, allowing for easier, more gentle application. The lanolin should then be lightly patted onto the entire nipple and areola area immediately after a nursing or pumping session.
Applying the product when the skin is still slightly moist helps the lanolin effectively seal in the natural hydration from the feeding session. This occlusive layer helps prevent further drying and cracking. Lanolin does not need to be wiped off before the baby nurses again, as it is safe for ingestion and free of taste or scent that might interfere with feeding.
Guidelines for Duration and Weaning Off
Lanolin is intended for temporary use while the nipple tissue adapts to the increased demands of frequent nursing. Initial soreness typically subsides as the baby’s latch improves and the skin acclimates, often within the first one to two weeks after birth. Once the nipples are fully healed and pain-free, the use of lanolin should be gradually discontinued.
The weaning process involves reducing the frequency of application, perhaps only using it once a day or only when a slight discomfort is felt. Lanolin treats the symptom of soreness but does not correct the underlying cause, which is often a shallow or improper latch. If pain persists beyond the initial adjustment period, continued lanolin application may mask a problem that requires professional intervention.
Signs Lanolin Use Should Be Discontinued
If soreness does not improve within a few days of consistent lanolin use, or if the pain suddenly worsens, contact a healthcare provider or lactation consultant. Lanolin should not be used as a substitute for diagnosing and correcting issues like an improper latch or tongue tie, which cause mechanical damage to the tissue. The application of lanolin should cease immediately if signs of infection appear, as this requires medical treatment.
Warning signs of a more serious issue include:
- Persistent, deep pain.
- Redness, swelling, warmth, or a sudden fever.
- The appearance of white, flaky patches on the nipple or areola, which could indicate a yeast infection (thrush).
- An allergic reaction, such as an itchy, tingling feeling or a rash, particularly if there is a known sensitivity to wool products.
Lanolin may exacerbate a yeast infection by creating a moist environment.
