NUK First Choice+ bottles have a physiological teat adapted to the baby's jaw, with a very soft soft zone shaped according to the shape of the mother's nipple during breastfeeding. Very well accepted by infants, this dummy is ideal for mums wanting to alternate breastfeeding and bottle. The built-in temperature control indicator changes from blue to white when the contents of the bottle is too hot. This ensures that your baby's milk is always at the right temperature. Thanks to its natural shape, the NUK dummy adapts perfectly to the child's sensitive palate and promotes the development of jaws and teeth, while the NUK Air System concept reduces colic pain and prevents the baby from swallowing air. Sturdy and BPA free, this bottle includes a locking plate to prevent any leakage during transport.
