Introduction
The Lansinoh NaturalWave Feeding Bottles are designed to support every feeding journey, whether bottle feeding, breastfeeding, or a combination of both. These BPA-free plastic bottles feature NaturalWave ultra-soft and strong silicone nipples with a wide base and gradual slope, promoting a secure latch that supports baby-led feeding. The clinically proven anti-colic system minimizes air intake, helping to prevent gas, fussiness, and spit-up for a more comfortable feeding experience. With a simple three-piece design (excluding cap), these bottles are easy to clean and assemble, making daily life easier for parents.

Setup
Before First Use
- Disassemble: Separate all components of the bottle: bottle, screw cap collar, and NaturalWave nipple.
- Clean: Wash all parts thoroughly in warm, soapy water. Use a bottle brush to ensure all surfaces are clean.
- Sterilize: Sterilize all parts using one of the following methods:
- Boiling: Place parts in boiling water for 5 minutes.
- Steam Sterilizer: Follow the manufacturer's instructions for your steam sterilizer.
- Dishwasher: Place all parts on the top rack of your dishwasher.
- Dry: Allow all parts to air dry completely or use a clean cloth.
Assembly
- Insert the NaturalWave nipple into the screw cap collar from underneath, pulling it through until it sits securely.
- Screw the assembled nipple and collar onto the bottle until tight.
- Ensure the anti-colic air ventilation system (small hole on the nipple base) is facing upwards when feeding to minimize air intake.

Operating Instructions
Filling the Bottle
- Ensure the bottle is clean and assembled correctly.
- Pour breast milk or formula into the bottle, using the measurement markings on the side for accuracy. The 8-ounce bottle has clear markings for both ounces and milliliters.
- Securely attach the nipple and collar assembly.
Feeding Your Baby
- Always check the temperature of the milk before feeding by placing a few drops on your wrist.
- Position your baby comfortably.
- Offer the nipple, ensuring your baby achieves a wide, deep latch, similar to breastfeeding. The flexible silicone nipple is designed to adapt to your baby's natural sucking motions.
- Observe the anti-colic air ventilation system to ensure it is positioned upwards to allow air to flow into the bottle, reducing the chance of your baby ingesting air.
- Allow your baby to control the flow of milk. The NaturalWave nipple is designed to deliver milk only when your baby actively sucks.

Nipple Flow Rates
Lansinoh NaturalWave nipples are available in various flow rates to accommodate your baby's developmental stage and feeding needs. The 8-ounce bottles typically come with a Medium Flow (Size M) nipple, suitable for babies around 3 months and older. Other flow rates (Extra Slow, Slow, Fast) can be purchased separately.

Maintenance
Cleaning
- After each use, disassemble all bottle parts.
- Wash immediately in warm, soapy water using a bottle brush for the bottle and a nipple brush for the nipple.
- Rinse thoroughly with clean water.
- The bottles and components are dishwasher-safe (top rack recommended).
Sterilization
Regular sterilization is important, especially for newborns. You can sterilize the bottles by boiling them for 5 minutes, using a steam sterilizer, or placing them in the dishwasher on a sanitizing cycle if available.
Storage
- Store clean, dry bottles in a clean, dry place away from direct sunlight or heat.
- The bottles are freezer-safe, allowing for convenient storage of expressed breast milk.

Troubleshooting
Nipple Confusion
The Lansinoh NaturalWave nipple is designed to minimize nipple confusion by mimicking the natural breast. If your baby is struggling to switch between breast and bottle, ensure a slow flow nipple is used and that your baby is actively sucking to draw milk, rather than having milk drip freely.
Colic, Gas, or Fussiness
The anti-colic air ventilation system is integrated into the NaturalWave nipple to reduce air intake. If your baby experiences colic, gas, or fussiness during feeding, ensure the air vent is positioned upwards and clear during feeding. Also, check that the nipple flow rate is appropriate for your baby's age and feeding style.

Leaking
If the bottle leaks, check the following:
- Ensure the screw cap collar is tightened securely onto the bottle.
- Verify that the nipple is correctly inserted into the screw cap collar and forms a tight seal.
- Inspect the nipple and collar for any damage or wear that might cause leaks. Replace if necessary.
