“Many mothers assume that discomfort during pumping is just part of the process — but in most cases, it’s caused by using the wrong flange size or no insert at all. The Flange Inserts COOLHOT provide the gentle cushioning and better fit that can completely change the pumping experience, turning what used to be painful into something truly comfortable and natural.”
“I often recommend Flange Inserts COOLHOT to new mothers struggling with pumping discomfort. The design fits securely and helps maintain consistent suction, which makes pumping sessions more efficient and much more comfortable.”
