A natural solution for colic, constipation, and other gas-related  problems, the Windi works instantly and does not require ingestion  of any drops or medication.   The Windi is a single-use tube that helps babies get rid of excess  gas.   Designed to be safe and effective, the Windi cannot harm your  baby if used as instructed.   Most pediatric professionals are familiar with the method of  using a rectal thermometer to relieve gas, colic, and constipation.   The Windi is designed specifically for this purpose. The soft,  pliable, hollow tube features a rounded tip that is long enough to  reach past the muscle that prevents the release of the gas, and  also has a stopper to prevent an insertion too far.   Each package contains 10 disposable Windis.
