How do the 3-speed systems in the round teat range work?Updated 2 days ago
The flow rate varies depending on the size of the slit at the end of the teat. The larger the slit, the more liquid can pass through, and therefore the higher the flow rate.
It is possible to adjust the opening of the slit. Depending on the orientation of the teat, the slit will be more or less open. This makes it possible to adapt to your baby's sucking rhythm in a single movement by turning the bottle.
