Hands-Free Wearable Breast Pump - Hospital Grade Cordless

Hands-Free Pumping That Fits Your Life

Problem: Traditional breast pumps chain you to a wall outlet and demand both hands, making it impossible to care for your baby, work, or simply have a cup of tea while pumping.

Solution: The Tiny Bloom Wearable Breast Pump gives you complete freedom. Slip it into your bra, press start, and get on with your day—no cords, no tubes, no sitting still required.

How It Works

The Tiny Bloom Wearable Breast Pump sits entirely inside your bra cup — no dangling tubes, no external motor unit. Here's how simple it is:

1. Choose your flange size using our free measuring card and insert the correct insert into the flange.
2. Assemble the 5 parts — flange, diaphragm, valve, milk stopper, and collection cup — in under 30 seconds.
3. Slip it into your bra and press the power button on the soft-lit touchscreen.
4. Start in Massage Mode to stimulate let-down, then switch to Expression Mode for efficient milk collection.
5. Adjust suction across multiple levels to find your perfect comfort setting — up to 324.7 mmHg hospital-grade suction.
6. Auto-shutoff kicks in at 30 minutes. Remove, pour milk into storage, rinse parts, and you're done.

The rechargeable battery lasts up to 2 hours per charge via USB-C, so one charge covers multiple sessions throughout the day.

Flange Sizing Guide

Getting the right flange size is the single most important factor for comfort, suction efficiency, and milk output. An incorrect fit can cause nipple pain, reduced output, and blocked ducts.

The Tiny Bloom pump includes a 25–27mm flange plus 19mm and 22mm inserts, covering the most common nipple sizes. To find your correct size:

• Measure your nipple diameter (not the areola) in millimetres — ideally after a pumping session when the nipple is at its largest.
• Your flange should be nipple diameter + 2–3mm of clearance. The nipple should move freely without the areola being pulled in.
• Use our nipple measuring card for an accurate reading at home.
• If you're between sizes, size up for comfort.
• Signs your flange fits correctly: nipple moves freely, no areola tissue is pulled in, no pinching or rubbing, and milk flows steadily within 2–3 minutes.

Who It's For

The Tiny Bloom Wearable Breast Pump is designed for mothers who refuse to put their life on hold to pump. It's ideal for:

• Working mums who need to pump discreetly at the office, in meetings, or during a commute without a dedicated pumping room.
• Mums of toddlers who need both hands free to care for an older child while expressing for a newborn.
• Breastfeeding mums building a freezer stash who want to pump frequently without it taking over their day.
• Mums with low supply who need to pump often and want a comfortable, hospital-grade option they can use anywhere.
• Mums returning to work who want a seamless transition that keeps their supply up without disrupting their schedule.
• Anyone who's struggled with traditional pumps — the cords, the noise, the sitting still — and wants a better way.

If you're exclusively pumping, combination feeding, or just starting your breastfeeding journey, this pump is built to support you.

Milk Output — What to Expect

Milk output varies between mothers and is influenced by supply, hydration, stress levels, time of day, and how well the flange fits. Here's what Tiny Bloom mums typically experience:

• First sessions: Output may be lower as your body adjusts to the pump. Most mums see improvement within 3–5 sessions.
• Established supply: Many mums express 60–150ml per session per breast, though this varies widely and is completely normal.
• Maximising output: Pump in the morning when supply is highest, stay hydrated, use the massage mode to trigger let-down before switching to expression mode, and ensure your flange size is correct.
• Collection cup capacity: 150ml per unit — sufficient for most single sessions. For high producers, have a storage bag ready.

The hospital-grade suction (up to 324.7 mmHg) is comparable to clinical-grade pumps, giving you efficient expression without discomfort when sized correctly.

Cleaning & Care

The Tiny Bloom pump has only 5 parts that contact milk, making cleaning quick and straightforward. The motor unit is never submerged — only the milk-contact parts are washed.

After every session:

• Disassemble the flange, diaphragm, valve, milk stopper, and collection cup.
• Rinse all milk-contact parts under warm running water immediately after use.
• Wash with warm soapy water or in a dedicated breast pump parts basin — do not wash in a shared sink.
• Air dry on a clean paper towel or drying rack. Do not use a cloth towel (can harbour bacteria).

Sterilising (recommended daily):

• Use a steam steriliser, microwave steriliser bag, or boil parts for 5 minutes.
• Our hospital-grade steam sterilisers are compatible and kill 99.9% of bacteria in minutes.

Part replacement: Replace the diaphragm and valve every 4–8 weeks for optimal suction performance. Worn parts are the most common cause of reduced output. Replacement parts are available in our store.

Storage: Store assembled pump in the included material bag between sessions. Charge via USB-5volt 1 amp plug after each use to ensure a full battery for your next session.

Frequently Asked Questions

Is the Tiny Bloom pump hospital-grade?

Yes. The suction reaches up to 324.7 mmHg, which is within the hospital-grade range. It uses both a massage (stimulation) mode and an expression mode, mimicking the two-phase pumping pattern used by clinical pumps.

What flange size do I need?

The pump includes a 25–27mm flange and 19mm and 22mm inserts. Use our measuring card to find your correct size. Your nipple should move freely in the tunnel with 2–3mm of clearance around it.

Can I use this pump if I have a low milk supply?

Yes. The hospital-grade suction and two-phase pumping pattern are effective for stimulating supply. Pumping frequently (8–12 times per day) and ensuring correct flange fit are the most important factors for supply building.

How long does the battery last?

Up to 2 hours of continuous use per charge. Charging takes 2–3 hours via 5volt 1amp USB-C. We recommend charging after each use so it's always ready.

Is it safe to use while breastfeeding my baby?

Yes — many mums use the wearable pump on one breast while nursing on the other to maximise output and save time. The hands-free design makes this practical and comfortable.

How do I know when to replace the parts?

Replace the diaphragm and valve every 4–8 weeks, or sooner if you notice reduced suction. These small parts wear with regular use and are the most common cause of declining output. Replacement parts are available in our store.

Is it BPA-free?

Yes. All milk-contact parts are 100% BPA-free and DEHP-free, meeting food-grade safety standards.

Can I use this pump at work?

Absolutely. The whisper-quiet motor and fully concealed design mean you can pump discreetly in an office, meeting, or any workplace setting without anyone knowing.
