Setup and Assembly
- Before First Use: Disassemble all parts. Wash thoroughly in warm, soapy water and rinse well. Sterilize by boiling in water for 5 minutes or using a sterilizer.
- Assembly:
- Insert the NaturalWave Nipple into the collar. Ensure the nipple is pulled through completely and securely seated.
- Fill the Lansinoh bottle with breast milk or formula.
- Screw the assembled nipple and collar onto the bottle until snug. Do not overtighten, as this can affect the nipple's function and cause leaks.

Operating Instructions
- Feeding Position: Hold your baby in an upright position during feeding.
- Latching: Encourage your baby to open wide and latch onto the wide base of the nipple, similar to breastfeeding.
- Paced Feeding: Allow your baby to control the pace of feeding. The flexible tip is designed to stretch and compress, mimicking natural sucking actions.
- Monitoring: Observe your baby for signs of comfort and proper milk intake. The Advanced Air Ventilation System (AVS) helps reduce air ingestion.

Care and Maintenance
- Cleaning: Wash all parts immediately after each use. Use warm, soapy water and a soft brush or sponge. Rinse thoroughly.
- Sterilization: Nipples can be sterilized by boiling for 5 minutes, using a steam sterilizer, or a dishwasher (top rack only).
- Storage: Store clean and dry nipples in a covered container. Keep away from direct sunlight or heat.
- Inspection: Inspect nipples regularly for signs of wear, tear, or damage. Replace immediately if any damage is observed.
Troubleshooting
- Leaking: Ensure the nipple is correctly inserted into the collar and the collar is securely, but not overly, tightened onto the bottle. Check for any damage to the nipple or collar.
- Slow Flow: If your baby seems to be struggling or taking too long to feed, consider if a faster flow nipple (Size S, M, or F) might be more appropriate for their age and development.
- Fast Flow/Choking: If your baby is gulping, choking, or spilling milk excessively, the flow rate might be too fast. Ensure you are using the correct Extra Slow Flow (XS) nipple for newborns.
- Nipple Collapse: Ensure the anti-colic vent is clear and not blocked. If collapse persists, the nipple may be worn and require replacement.
