DESCRIPTION: Replacement tubing for the SleepyMommy Adapter. Length: 20 inch. Pack of 2. Please replace every month. Since it's a very long tubing, we recommend cutting it as short as possible because it would minimize milk pooling inside the tubing and allow easier cleaning. To clean the tubing, please use a children's medicine syringe (not included) to inject warm soapy water and then clean tap water to rinse.
