Use and safety instructions on inside carton flaps.

Care: Disassemble before cleaning. Prior to first use, sanitize by boiling in water for 5 minutes. For day to day cleaning, wash with hot water and mild detergent then rinse clean. Dishwasher-safe (top rack). Allow to dry before storage.

Use: The vent on the nipple should be under baby's nose, feeding holes will be facing upwards. To heat, place the bottle in a container of warm water. For hygiene and safety, replace with appropriate NUK® nipples after about 2 months of use. Can be used with all NUK® Simply Natural™ nipples.

Caution: Do not overheat. Always test temperature of liquid on wrist before feeding baby. Do not microwave, since this can cause uneven heating. Always supervise baby when feeding. To avoid injury, do not allow a child to walk or run with a bottle.

Warning: To prevent possible choking hazard, test strength before each use by pulling the nipple in all directions. Any tear can lead to the separation of pieces. Discontinue use if any tear or crack appears. Do not attempt to enlarge the holes as this may lead to tearing.
Prolonged periods of time drinking liquids, other than water, may cause tooth decay.

Electric Bottle Warmer Usage: We recommend warming this bottle in a container of warm water. If an electric bottle warmer is used, the rapid heating can weaken the material over time such that it could break if dropped.
