Disney Princess Pack of 3 Baby Feeding Bottles provide a complete line of feeding solutions for your baby's changing needs. The iconic classical shape of the feeding bottle helps the baby to have a good grip over the bottle and moms can comfortably hold them for a long time. These uniquely shaped are paired with venting technology. Expertly designed for easy assembly and leak-free feeding, the simple, one-piece integrated nipple and vent system means no extra parts to clean or lose. These soft silicone nipples rapidly vent, directing air bubbles into the bottle, not baby's tummy, which significantly reduces gas, colic, and fussiness. To help take the guesswork out of feeding your little one the Vented + Polypropylene Bottles feature molded measurement markers in both ounces and milliliters to provide an easy and accurate way to measure the volume of liquids without the risk of the measurements washing off. The unique shape, based on Disneys flagship design with a lightweight, helps to make these bottles simple to hold, simple to use, and simple to love. Rest assured, our bottles are 100% free of polycarbonates, PVC and phthalates, and are also made of food-grade material. WARNINGS: Never use feeding nipples as a pacifier. Continuous and prolonged sucking of fluids will cause tooth decay. Always check food temperature before feeding. Always check the nipples for signs of wear and replace when damaged. Do not use a microwave oven to heat the bottle because microwave ovens can create hotspots in milk/formula or bottle components. Do not leave the product in direct sunlight or heat or leave in disinfectant (sterilizing solution) for longer than recommended, as this may weaken the nipple. When used and sterilized intensively, nipples may deteriorate after 6 weeks. CAUTION: Remove the bottle from your babys mouth when the baby is not feeding. Do not let a child take a bottle to bed or self-feed for long periods. Prolonged contact with milk, formula, and other liquids can cause tooth decay. Allowing your child to use this product for prolonged periods separate from regular mealtimes or to go to sleep while drinking liquids, other than water, from this baby bottle may cause or contribute to early childhood tooth decay. Be sure to contact your physician should you have any feeding problems or questions.
