Proper Hygiene & Sterilization Guidelines

Before each use and before the first use, please thoroughly wash each part of the nipple and baby bottle before sterilizing,

Especially, use a nipple puncher or nipple brush to clean and open the nipple hole for the first time, and expand the nipple hole and anti-spill valve.

Attention, Moms!

The anti-spill valve is designed to prevent milk splatter and over-inflation. If your baby sucks vigorously or is very hungry, the nipple may become compressed or blocked. In such cases, Aoi recommends using a nipple puncher or nipple brush to clear the anti-spill valve.

If your baby suddenly becomes reluctant to bottle-feed, you can switch to a larger nipple size to accommodate your baby’s faster and healthier feeding ability!

Removable parts such as the bottle body, nipple, and sealing cap should be soaked in boiling water for 2 – 3 minutes. Over-soaking can damage and reduce the lifespan of the nipple and baby bottle.

Keep the water bottle fully submerged in boiling water.

Soak for approximately 2 – 3 minutes.

Ensure the water for cleaning the baby bottle is at a sufficient temperature.

Allow all parts to cool before use and drain any trapped water inside the nipple to ensure maximum hygiene.

In subsequent uses, moms can sterilize in the microwave or sterilizer.
