After six months, milk will no longer be the only exclusive food for the baby, and other liquids and complementary foods should be introduced into his or her diet. Fruits and juices, due to their high content of minerals, vitamins, and other nutrients, play an important role in the child’s health. However, due to their higher viscosity than milk, juices require a special and dedicated system to transfer them from the bottle to the nipple. This system should prevent bloating and discomfort during feeding and make the child enjoy the taste of the juice, encouraging him or her to drink it.
