For your child’s safety and health WARNING!
Always supervise your child when using this cup. Prolonged sucking of fluids may cause tooth decay. Never attach the cup to cords, ribbons, laces, or clothing — strangulation hazard. Do not extend or modify cords or loops. Keep unused parts out of reach of children.
Before first use, disassemble all parts and boil for 5 minutes to sterilize. Clean thoroughly before each use. Top rack dishwasher safe, but handwashing is best to preserve printed designs and prevent fading. Avoid abrasive cleaners or rough sponges.
Before each use, inspect the lid, cup base, and any spout, straw, or nipple. Pull the nipple, spout, or straw in all directions and discard at the first signs of damage or weakness. Never use a spout, nipple, or straw as a soother.
Handwash in warm soapy water using a clean basin reserved for infant items (not directly in the sink). Rinse well. If using a sterilizer, separate all parts and clean before sterilizing. Ensure all parts are dry before reassembling or storing. Do not leave in sterilizing solution longer than recommended. Avoid direct sunlight or high heat for extended periods.
Do not use with hot (over 45°C / 113°F), carbonated, or sugary drinks. If using warm liquids, open carefully — pressure may build and cause spray. Flush through spouts or straws with clean water to remove any residue. Some drinks may stain the cup, but this won’t affect function.
Avoid microwave use with the lid or any metal components. Take extra care when heating — localized overheating may occur. Wait 15 minutes between microwave cycles. Always stir and test the temperature before serving.

FAQs
What moms want to know
Yes, your baby can enjoy warm or cold liquid in the Starter Set (max 45°C or 113°F). Always remember to test the liquid temperature before giving it to your child.
Yes, you can warm liquid in the base of the Starter Set Cup. Do not attach any lids while microwaving or include the weighted sippy straw. Always test the temperature of the liquid before serving. As a general guide, warm milk for about 20 seconds per 6 oz in the microwave.
We do not recommend it. The no-spill valve may make formula too thick to pass through, and residue buildup can be hard to clean. Formula is best used with our NaturalWave nipple lid, spout cups, or training cups. Always wash all parts thoroughly after each use.
No. The cup is designed to be free flow, helping kids learn to drink from an open cup.
