The natural motion of babies while sucking out milk is enhanced by Pigeon peristaltic bottles. The nipple of the bottle has suction similar to that of an accordion which encourages natural tongue motions. The material of the nipple is soft and flexible so there are smoother tongue movements. The elasticity of the nipple is also kept the same as a mother's breast so that the baby is comforted while feeding.

The innovative Air Ventilation System (AVS™) also enhances the feeding process. It controls the air pressure inside the bottle so that milk flow is equal. This eliminates chances that the baby will swallow too much milk and choke. The AVS also helps reduce air bubble intake by the baby which can often cause problems such as colic.
