The NUK Perfect Match baby bottle is ideal for your baby, thanks to its adaptive design. The bottle's nipple is uniquely soft and elastic, just like a mother's skin, so it gently adapts to the baby's lips and palate. The slightly conical shape facilitates the correct hold: mouth open with lips covering the nipple. The innovative Anti-Colic valve helps prevent air ingestion, offering 3 nipple sizes that adjust the milk flow in the best way for your baby. Ensuring the ideal milk temperature is simple thanks to the built-in Temperature Control Indicator on the side of the bottle, which changes color from blue to white when the bottle's contents are too hot.
