Rinse thoroughly and dry carefully using a cloth. Do not use abrasive or aggressive products. Then, place the teat in boiling water for 5 minutes. Allow to cool before use. Clean before each use. It is advisable to rinse the teats with plenty of water to remove food residue immediately after each use. Always check the temperature of the food and/or feed before feeding. Before giving milk or other food and/or drink to the child, check that the flow is adequate for the child's needs, especially with younger babies. From a practical point of view, it may be useful to observe whether the child becomes excessively tired during feeding or if, on the contrary, milk leaks from the mouth. When the product is completely dry, store it in a clean, dry place, protected from direct sunlight and heat sources. PRECAUTIONS AND WARNINGS Cleaning: Do not wash the teats in the dishwasher. After washing, it is recommended to carefully rinse the bottle and its accessories under running water. The teats can be disinfected cold using sterilizing liquids or hot (steam) using appropriate devices, or by boiling them for 5 minutes. Clean before each use. It is advisable to rinse the teats with plenty of water to remove food residue immediately after each use. When the product is completely dry, store it in a clean, dry place, protected from direct sunlight and heat sources. Do not immerse teats in sweet or medicinal substances, as this may promote the formation of cavities. Always use this product under adult supervision. Never use the teats as a pacifier. Continuous and prolonged sucking of liquids can cause cavities. Always check the temperature of the food before feeding. Before giving milk or other food and/or drink to the child, check that the flow is adequate for the child's needs, especially with younger babies. From a practical point of view, it may be useful to observe if the child becomes excessively tired during feeding or if, on the contrary, milk leaks from the mouth. We recommend using these teats only with Step Up Baby Bottles from the Chicco product line. Always check that the diameter of the teat corresponds to the diameter of the bottle's mouth. Carefully inspect the teat before each use and pull it in all directions. At the first sign of deterioration or fragility, do not use the product and replace it. Do not leave the teat exposed to direct sunlight or near heat sources, and do not leave it immersed in the appropriate sterilizing solution for longer than recommended, as this could damage and weaken the teat. It is advisable to change the teat at least every two months or before it shows signs of wear, such as cracks, swelling, color changes, or if it becomes sticky. Before using it for the first time, place it in boiling water for 5 minutes. This is for hygiene reasons. Silicone is a material that breaks easily, so it is not recommended to use it when the first teeth appear, as this could damage the teat, creating fragments and/or small parts that could be swallowed by the child.
