Correct use of a breast shield is crucial for its effectiveness: - Size Matters: Ensure you are using the right size of shield that fits your nipple properly. Ill-fitting shields can cause discomfort or reduce milk transfer. - Positioning: Place the shield so that your nipple is centered in the shield's opening. The shield should adhere closely to your breast. - Latch: Encourage your baby to latch onto the shield just as they would latch onto the breast.
