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.
To heat, place the bottle in a container of warm water. For hygiene and safety, replace nipples after about 2 months of use. The vent should be under the baby's nose. Can be used with most narrow nipples.
Note: Performance guaranteed under normal use.
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. Do not attempt to enlarge the hole since this will affect product performance.
To prevent possible choking hazard, test strength before each use by pulling the nipple in all directions. Discontinue use if it becomes sticky, enlarged, cracked, torn, or shows other signs of excessive wear. Prolonged periods of time drinking liquids, other than water, may cause tooth decay.
