Many silicone collectors rely on suction and are made from a fully soft silicone body, which can make the fit bulkier and more likely to shift or compress inside a bra. Mothers in our consumer survey who had used the Haakaa Ladybug collectors commonly reported that these designs were difficult to wear discreetly, awkward in public, and impractical for sleep due to their bulky size. Some also noted pinching of the skin and a higher risk of spilled milk. The Bosom Ritual Shells were created to address these concerns, using a structured, low-profile outer shell, designed to hold its shape under clothing and reduce the likelihood of compression or tipping. With a dual-purpose function; breathable airflow mode for upright wear and sealed leak-proof mode for movement or rest, they are intended to adapt more easily to real daily and overnight routines, rather than requiring mothers to plan their movements around a bulky collector. This is modern breast care without compromise.

Milk production is influenced by how much milk is removed from the breast. Devices that use suction or actively draw milk out can increase milk removal, which for some mothers may signal the body to produce more milk, resulting in an unwanted oversupply.

The Bosom Ritual Shells are designed for passive milk collection only. They do not use suction and do not actively stimulate milk ejection. Instead, they collect milk that your body naturally releases during let-down or spontaneous leakage.

Because every body responds differently, particularly in the early postpartum weeks when supply is regulating, any form of additional milk removal may influence supply for some mothers. If you are managing oversupply, breast inflammation, or discomfort, it is safe to use the Mammae breast milk collectors however we always recommended seeking guidance from an IBCLC or qualified health professional based on your individual feeding goals.

No. They are not a breast pump and are not designed to actively express milk. They gently and naturally collect milk that is already flowing from the breast during and between breastfeeding or pumping.

Passive collection means no intentional suction and no active stimulation to draw milk out. Milk is collected only if your body releases it naturally (e.g. during let-down or spontaneous breast milk leakage).

It depends on the device and how it’s used. Collectors that create active suction (even unintentionally) can increase milk removal, and increased removal can signal the body to produce more for some mothers (a common concern discussed in breastfeeding communities). The Mammae Bosom Ritual Shells are designed to avoid suction-based collection, especially in the early weeks when supply is regulating between the mother and baby dyad.

You can choose:

• Breathable airflow mode (plugs removed) for gentle ventilation when upright or resting.
• Sealed leak-proof mode (plugs inserted) for movement, side-lying feeds, and overnight wear.

This is designed to match the reality that a mother’s needs change throughout the day and night.

The optional breathable function is best used when you want ventilation and you’re mostly upright (feeding, seated rest, desk work). It’s generally not the best choice for any active, vigorous movement or bending, because the airflow openings are not sealed and this will result in spilled milk. For mothers busy on the go, with younger active children, tending to household chores etc, using the leak-proof function is recommended.

Use the sealed mode when you need secure leak-proof protection: on-the-go movement, overnight wear, side-lying feeds, household chores, or any time you want the airflow openings fully closed as needed to prevent spilled milk.

Many mothers can, particularly in the sealed leak-proof function. Comfort and leakage risk can vary by breast fullness, sleep position, and bra fit. If you experience pressure, tenderness, or frequent fullness, consider shorter wear periods and reassess.

They’re designed for low-profile, discreet wear, but visibility depends on personalised bra style, fabric thickness, breast size/shape, and outfit. A supportive nursing bra or tank typically offers the most invisible fit.

Moisture management matters. Any wearable device can trap moisture depending on material, fit, and duration of wear. The Mammae Bosom Ritual Shells offer an optional airflow function to support ventilation when appropriate. Regardless of device, it’s typically helpful to ensure the skin is dry before placing breastfeeding aids back on.

Yes. Many mothers use our passive breast milk collectors on the opposite breast during a feed to catch and collect let-down. The breast milk collected can be fed directly to your baby from the shell like a cup or safely poured and stored.

Some mothers choose to use collected breast milk in other nurturing ways, such as adding a small amount to their baby’s bath water or using it for gentle skin care on areas of dryness. Others may use a few drops for cleaning and soothing sticky eyes, or to moisten cotton wool for gentle skin cleansing during nappy changes.

These uses are optional and personal, and are based on traditional and anecdotal practices rather than medical treatment. If your baby has broken skin, signs of infection, or persistent irritation, seek advice from a qualified health professional.

Each shell has a capacity of 25ml. If you tend to have a strong let-down, you may need to empty more frequently.

Remove the Bosom Ritual Shell, keeping the airflow openings positioned upright. If wearing in breathable mode, pour the milk slowly from the opposite side of the Shell (the side with the logo), rather than from the airflow openings, to help prevent leakage.

If you prefer to pour from any angle, first insert the silicone plugs to seal the airflow openings, then pour gently into a clean, sterile container. When time is limited, such as during night feeds or while out, sealed mode can help reduce the risk of accidental spills before you reach a safe place to empty.

Wash with warm water and mild soap after use. They’re compatible with steam or UV sterilisation, and can be boiled briefly as per your product instructions. Let all parts dry fully before reassembling and usage.

Breast inflammation has multiple contributors (milk removal patterns, pressure/compression, oversupply dynamics, etc.). Any product that causes excess pressure or encourages extra milk removal may be a factor for some mothers. Contemporary clinical guidance recognises a mastitis “spectrum” and cautions against excessive pumping in the case of inflammatory mastitis. If you have fever, rapidly worsening symptoms, severe pain, or concern for infection, seek prompt medical care from an IBCLC, midwife or health care professional.

Bosom Ritual Shells are made from food-grade polypropylene (PP) and silicone. The materials have been independently laboratory tested and verified to be free from BPA, lead, and phthalates, in accordance with applicable safety standards for food-contact and infant-related products. They are designed to be skin-safe, durable, and suitable for repeated sterilisation using steam, UV, or brief boiling, when used as directed.
