Nuk Nature Sense Baby Bottle with Silicone Teat T1S 0-6M presents an innovative teat, with an extra-soft and especially flexible area, which adapts to the baby's mouth, such as the mother's nipple. It incorporates an anti-colic valve, which allows the baby to drink without interruption, such as the mother's breast, avoiding the intake of air, sometimes responsible for colic. The multiple holes in the teat ensure a constant and natural milk flow. The protective cap closes all the holes in the teat completely tight. Teat material: silicone. Teat size: 1 - suitable for children up to 6 months. Orifice size: S - small orifice, suitable for breast milk, water or tea.
