Dual Purpose Breast Milk Collectors

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.
