The Physiological Anti-Colic Valve Teat is particularly soft and elastic, thus simulating the physiology of the maternal breast as close as possible.  It is intended for use with the Chicco plastic or glass feeding bottles.

• Special Length: Specifically design to simulate the nipple during sucking:  it lengthens twice as much with respect to its normal rest position. 
• Ribbed Rings: Increases the natural elasticity of natural latex rubber, allowing the teat to lengthen and giving it a texture similar to that of the maternal nipple.
• Large Base: Ensures maximum support for the baby's lips and helps sucking.
• Anti-Colic Valve: Avoids the swallowing of air and helps to reduce colic, hiccups and regurgitation.
• Available in 3 sizes:  0m+ : 2m+ : 4m+
