The SX Pro Physiological Teat keeps the tongue in the same physiological/natural position as when the baby is breastfeeding. Designed with the specific oral and dental characteristics of babies, whose maxilla and mandible are still developing, it follows the most advanced professional recommendations to avoid interfering with the development of the oral cavity. Endorsed by the Spanish Society of Pediatric Dentistry and recommended by the Italian Association of Physiological Orthodontic Specialists. Flat and symmetrical: This is the shape most recommended by Pediatric Dentists¹. It leaves more space for the tongue in the oral cavity so that sucking is as natural as possible². Longer neck² -> 20mm: Reaches the junction of the hard palate with the soft palate, as recommended by scientific studies³ to achieve a more natural suction. Neck centered with respect to the base -> 90°: The most comfortable for the baby who picks up the bottle alone. Anti-colic valve: Allows pressure to be balanced between the outside and inside of the bottle. Slightly bulging concave base: Ensures that the mouth, tongue and jaw muscles are positioned correctly. It allows greater adaptability, since a newborn baby will rest their lips in the center of the base, while an older baby with a larger mouth will be able to place their lips almost on the outer edge, taking the entire teat into their mouth. It allows the tip of the teat to reach more or less behind the palate, depending on as the baby grows. Ultra-soft, fine silicone with a sandblasted finish mimics the texture and consistency of the mother's nipple, achieving: Maximum warmth. A super-flexible movement². Maximum adaptation to the shape of the palate². Prints 270ml bottle, new bottle, straight shape that offers a more comfortable grip for the baby. With a medium-flow SX Pro physiological teat, from 3 months, it allows all types of medium-density liquids to pass through, ideal for milk, juices or water
