Key Features
Anti-Colic Venting System
The NUK Smooth Flow Pro bottle is engineered with an advanced anti-colic venting system. This system is proven to significantly reduce common colic symptoms such as gas, extensive crying, and reflux by minimizing air bubbles swallowed by the baby during feeding. This leads to less spit-up and burping.

One-Piece Nipple & Collar Design
The innovative one-piece integrated bottle nipple and collar design simplifies preparation, assembly, and cleaning. This seamless construction also guarantees no leaks, providing a mess-free feeding experience.

SafeTemp Indicator
Each bottle is equipped with a SafeTemp indicator that changes color when the milk is too hot, ensuring optimal feeding temperature for your baby.

Setup and Assembly
The NUK Smooth Flow Pro bottle is designed for quick and easy assembly.
- Ensure all components (bottle, one-piece nipple/collar, vent cleaning brush) are clean and sterilized before first use.
- Insert the vent cleaning brush into the vent tube located within the one-piece nipple/collar assembly.
- Align the assembled nipple/collar with the bottle opening.
- Twist the nipple/collar clockwise until securely fastened to the bottle. Do not overtighten, as this can affect nipple function.
- For Learner Cup assembly, attach the soft silicone spout and handles to the bottle as needed.
Operating Instructions
Filling the Bottle:
- Unscrew the nipple/collar assembly from the bottle.
- Pour the desired amount of formula or breast milk into the bottle. Use the measurement markings on the side for accuracy.
- Re-attach the nipple/collar assembly, ensuring it is securely tightened to prevent leaks.
Checking Temperature with SafeTemp Indicator:
- The SafeTemp indicator is located on the side of the bottle.
- If the indicator is blue, the milk is at an appropriate temperature for feeding.
- If the indicator turns white, the milk is too hot and should be allowed to cool before feeding.
Feeding:
- Ensure the nipple is properly aligned and the vent is clear.
- Position the bottle so the nipple is full of milk, minimizing air intake.
- Monitor your baby for signs of comfort and proper milk flow. The unique Y-cut nipple design allows the baby to control the flow based on their suction.
Care and Maintenance
Proper cleaning and sterilization are crucial for your baby's health.
Disassembly for Cleaning:
- Unscrew the one-piece nipple/collar assembly from the bottle.
- The vent cleaning brush can be detached from the nipple/collar for thorough cleaning of all parts.
Cleaning Instructions:
- All components are dishwasher safe (top rack recommended).
- For hand washing, use warm, soapy water and rinse thoroughly.
- Use the provided vent cleaning brush to ensure the anti-colic vent tube is free of milk residue.
- Ensure all parts are completely dry before reassembly or storage.

Sterilization:
- The bottles and components are safe for use in standard sterilizers and bottle warmers.
- Follow the instructions of your specific sterilizer or warmer for best results.
Troubleshooting
Leaking:
- Issue: Bottle leaks when mixing or warming.
- Solution: Ensure the nipple/collar assembly is securely fastened to the bottle. Avoid overtightening. If mixing formula, consider mixing in a separate container and then pouring into the bottle. When warming, ensure all components are properly assembled after warming.
Nipple Collapse:
- Issue: Nipple collapses during feeding.
- Solution: This can occur if the bottle is too tightly sealed, preventing air from entering through the vent. Loosen the nipple/collar assembly slightly. Ensure the anti-colic vent is not blocked by milk residue; clean it thoroughly with the provided brush.
Difficulty Cleaning:
- Issue: Residue remains after cleaning.
- Solution: Disassemble all parts completely. Use the vent cleaning brush for the internal vent tube. For stubborn residue, soak parts in warm, soapy water before scrubbing. Ensure regular cleaning after each use.
