Tommee Tippee Advanced Bottle Advanced The decorated anti-colic bottle from the Advanced series is designed to ensure optimal ventilation during feeding. Thanks to the unique air tube, the anti-colic valve, and the special shape of the nipple, the baby swallows as little air as possible. Before giving your child a bottle, check the tube with the heat sensor. If it is blue, the milk is at the right temperature; if the color has changed to pink, the milk temperature is above the recommended temperature of 37°C. The anti-colic nipple is made from naturally soft silicone and has a unique shape that makes it easier for the baby to latch on.
