What is a silicone pump?
A constant-suction hand pump is a silicone unit with a bulb-shaped milk collection reservoir (bulb) at the bottom and a breast shield at the top. It attaches to the breast by suction created when the reservoir is squeezed, then placed on the breast and released. Constant-suction pumps are easy to wash, cheap, portable, and do not require electricity or hand action. Some mothers find that constant-suction pumps remain attached without support. Others need to hold it in place. It depends on the size and shape of the breast. Mothers can use this pump on one breast while breastfeeding on the other. It is best for a mother with a good let-down and a large milk supply. There is not much research to recommend it to mothers who are only pumping and not breastfeeding but there are positive reports online. Mothers who have painful breast problems can add clean, warm water to the pump to aid milk removal and decrease swelling of the area just behind the nipple.
