Nuk First Choice+ 300ml Anti-Colic PP Baby Feeding Bottle with temperature control is designed to make feeding your baby safer and more convenient by helping you monitor the temperature of the contents in the bottle. The Nuk teat, designed to mimic a mother's nipple during breastfeeding, offers several features to provide a natural and comfortable feeding experience for babies. The original Nuk teat is modeled after a mother's nipple to provide babies with a familiar shape and feel while feeding. This design takes into consideration the need for sufficient tongue and jaw movement, just like during breastfeeding. The tip of the silicone teat has a soft zone that optimally fits against your baby's palate. This design aims to create a natural and comfortable sensation for the baby while they are drinking. The Nuk Anti-Colic Air System is integrated into the teat design to ensure a natural flow of milk. This feature helps babies drink without swallowing excess air, which can lead to colic and discomfort. A reduced intake of air can contribute to a happier and more comfortable tummy for the baby. The Nuk teat has been clinically tested to ensure its effectiveness and safety for babies. This testing process confirms that it is well-accepted by infants, making it a suitable choice for babies who are both bottle-fed and breastfed. Nuk First Choice+ 300ml Anti-Colic PP Baby Feeding Bottle is made of light and shatterproof polypropylene. This material choice provides durability and ensures the safety of the baby while using the bottle. The baby bottle has the innovative feature, temperature control indicator is embedded within the graduation marks of the bottle. It acts like a thermometer, changing color based on the temperature of the liquid inside. When the liquid inside the bottle is at an ideal temperature, which is approximately body temperature (37°C or 98.6°F), the indicator will show a mean blue tone, indicating that it's safe for feeding. If the liquid is too hot, the normally blue indicator will turn white. This color change serves as a warning that the contents are too hot and should be allowed to cool before feeding your baby. The temperature control feature is integrated into Nuk First Choice+ bottles made of polyamide and polypropylene. Overall, the Nuk teat and bottle are designed to provide a natural and comfortable feeding experience for babies, with an emphasis on mimicking the mother's breast as closely as possible to promote acceptance and ease of transition between breast and bottle feeding. Also, it offers a helpful way to monitor the temperature of bottle contents and ensure that they are neither too hot nor too cold for your baby, promoting relaxed and safe feeding.
