This is a hospital-graded nursing bottle teat, which is produced for Low Birth Weight infants with weak sucking skills, with respiratory problems and / or cardiovascular problems, who need less stress during sucking. The teats are designed based on a sucking study that found out that LBW infants need a smaller teat diameter and softer materials. The teats are made of a hygiene-confirmed silicone material, which allows for its use in hospitals and clinics with the autoclave sterilization system (high-pressure steam sterilization device).
