Description Yoomi Gold is a self-warming feeding bottle set for babies from the first day of life, suitable for use with both breast milk and formula milk. Package contents The set includes a 140 ml anti-colic bottle, a 0 m+ slow-flow teat, a gold bottle collar and a warmer. Product purpose The products are designed to quickly warm and feed milk to babies, and the included slow-flow teat allows feeding newborns from the first day of life. Product characteristics The Yoomi Gold set is crafted with the utmost care for babys safety. The soft silicone nipple and bottle have a total of six holes that prevent air bubbles from entering the milk, preventing colic. The warmer, thanks to its channel system, warms the milk flowing through it to a temperature of 32-34°C, which corresponds to the temperature of mothers milk while preserving all its nutrients. The natural shape of the nipple and the heat it emits resemble a mothers breast, making it much easier for your baby to adapt to bottle feeding. All components of the set are designed for repeated use. After preparing the food, the warmer will slosh when shaken or will not make a sound. To recharge it, simply boil it in boiling water. When ready to use, the warmer will rattle when shaken, and its lifespan allows it to be recharged up to 300 times. All products included in the set are made of BPA-free materials. Product use Heating milk: 1. Place the collar over the bottle nipple until you hear a gentle click. 2. Place the warmer in the collar and screw on the food bottle. 3. Press the orange button firmly, after a few seconds you will feel warmth. 4. After 30 seconds, put the cap on the bottle and turn it upside down. 5. After another 30 seconds, begin feeding. If you are feeding without warming the food, place the teat and collar on the milk bottle and close the bottle, leaving a small space between it and the collar. Charging the heater in boiling water: 1. Boil water in a pot, place the heater in the boiling water so that it is on its side and completely immersed in the water. 2. Cook the device for 30 minutes. 3. Remove and let the warmer cool (75 minutes at room temperature or 20 minutes in cold water). Sterilization: 1.
