Nuk My First Genius Silicone Pacifier T1 0-6M has characteristics that make it unique: concave shape, which allows maximum freedom for tongue movement; integrated channels along the teat, which reduce pressure on the jaw, and continuous contour lines, which strengthen the teat and provide additional safety. The lip disc of the pacifier is anatomical, adapting perfectly to the baby's face - it has enough space for the nose and breathing, even in newborns. It incorporates the Nuk Air System, so the air exits through a valve when the teat is pressed. In this way, the pacifier remains soft and straight, preventing malformations of the jaw. It has an asymmetrical shape, so its inverted use is easily noticed. Made of silicone, a material with a smooth, odorless and neutral flavored surface, extremely resistant to high temperatures and sunlight. Size: 1, recommended for babies from 0 to 6 months. Nuk Nature Sense Baby Bottle with Silicone Teat features an innovative teat with an extra-soft, especially flexible area that adapts to the baby's mouth, just like the mother's nipple. It incorporates a valve that allows you to drink without interruption, such as the mother's breast, and prevents the ingestion 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. The size 1 bottle with three holes is ideal for breast milk, tea or water, and is suitable for children up to 6 months. The bottle size 2 and six holes is ideal for formula milk and is suitable for children between 6 and 18 months.
