Model # 17211: The Ameda Flexishield Areola Stimulator is a comfortable, flexible insert that fits any Ameda breast shield to provide increased stimulation to the areola. It mimics the feel of a baby's mouth, and helps stimulate the let-down reflex. The Flexishield can be helpful for mothers with engorgement, allowing for a softer more flexible surface to be in contact with the breast. It also reduces shield size for maximum effectiveness with smaller breasts.
