The jewel nipple was inspired by the hope of creating a nipple that could accommodate more infants, and is the result of repeated research based on feedback from all of the mothers that use Bétta's products. The design passed rigorous tests on factors such as the size of the opening, the ideal softness of silicone rubber, how easily the air valve opened, and a tolerance to deforming. The design facilitates your baby's natural instinct to “want to drink”. There are 2 replacement bottle nipples in each box.
This [round hole] type features a round hole at the end, which lets a certain amount of milk to flow out when tilted. It is designed to put milk on the tongue to trigger the baby’s "drinking" instinct.
