My 5 month old has a MIC-KEY and an Infinity pump. He's on continuous feeds and his EleCare 24 cal settles in his extension tube. We clean it three times a day, but after a few days, we just can't seem to get it clean. Our insurance pays for 4 extensions per month, but we need more. Does anybody have a source for buying the 12 or 24 inch hoses out of pocket at a reasonable price?
