What is aLu?

aLu is a device that reduces backwash contamination of breast milk during bottle feeding. Without aLu, leftover milk in your baby's bottle is contaminated by millions of bacteria from saliva. With the aLu device, leftover milk is uncontaminated by saliva, leaving it fresh for longer periods of time. When the baby is done drinking, just remove the nipple, nipple ring and aLu device and put the leftover milk in the refrigerator. When baby is ready to feed again, put on a fresh nipple and nipple ring, and baby is ready to drink every last drop of precious, liquid gold breast milk!

Why is backwash a problem?

Backwash is made up of millions of bacteria from your baby's mouth. Once backwash enters the breast milk through the bottle's nipple, it can feed off of the nutrients in the milk and rapidly grow. We do not see why all of the breast milk needs to be contaminated, so we set out to solve that problem! Now, when you re-feed your baby that bottle (following Center for Disease Control guidelines, of course), you are decreasing the amount of additional bacteria your baby is exposed to.

Can I use aLoo without the nipple?

No. A child should not suck directly on the device. This will affect the valve from preventing liquid from re-entering the bottle.

  • Sucking on the valve will contaminate contents of the entire bottle
  • Directly sucking on the valve is a potential choking hazard
  • How do I use aLoo?

    Insert your choice of nipple into the nipple ring. Once nipple is secured, insert aLu under the nipple, within the nipple ring. aLu should fit snugly up against the nipple. Once placed into the nipple ring, screw the cap onto the top of the bottle and begin feeding. For Philips Avent and Tommee Tippee skus, you may need to prime the nipple before feeding. If the milk does not passively flow into the nipple when bottle is tipped, please lightly squeeze the nipple as you give to your infant. This will let liquid to initially flow into the nipple and your infant will be able to feed without ingesting excess air. Please contact us with any questions.

    Which bottles are compatible with aLoo?

    At this time, aLu is compatible with Philips Avent, Dr. Brown's (Original and Natural Flow, Standard Neck only), Medela and Tommee Tippee only. The Philips Avent size fits the Anti-colic and Natural Feeding bottles. The Dr. Brown's size fits the standard narrow neck bottle. We are developing additional sizes that will be compatible with other bottles (Comotomo, Kiinde). Sign Up for Updates!

    Do I need to sterilize aLu prior to using?

    We recommend washing aLu prior to use, either by hand or in the top rack of the dishwasher. The aLu device does not need to be sterilized, but you can, if you choose. Simply place aLu in boiling water for three minutes, remove and dry before use.

    Does aLu interfere with the bottle's anti-colic vent?

    aLu also has an anti-colic air vent that allows air to flow back into the bottle, but the backwash contaminated milk does not! We have engineered the design to ensure it will not interfere with existing anti-colic mechanisms in your existing bottle (Dr. Brown's, Philips Avent, Tommee Tippee). When using aLu with these bottles, our device is meant to be used in addition -- not a replacement.

    How long can I reuse the breast milk if I warm it?

    We do not recommend that parents warm breast milk because at warmer temperatures, there is a drastic loss of immunity fighting proteins and a breakdown of fatty acids. (click here for study) For parents who DO save leftover milk, and re-feed that milk at the next feeding, we wanted to prevent the ADDED bacteria in the baby's saliva from unnecessarily contaminating the bottle of milk. We hope aLu helps parents who struggle with a limited supply of breast milk feel better if they do end up re-feeding leftover breast milk at a later time.

    Do you ship internationally?

    Yes! Everyone should be able to receive an aLu device! However, our shipping rates do not cover VAT taxes that some countries charge. When shipping internationally, we may be able to help if the device is held in customs. Please contact us if this occurs.
