Blue Lock Ultra Absorbent and Leak-Proof Disposable Nursing Pads are capable of holding up to 20 times their own weight without losing their shape. They are, without a doubt, one of the most used items during breastfeeding and a must-have in the basket you need to take to the hospital on the day of delivery. Breasts can leak when they are full of milk or when the hormone oxytocin triggers the let-down reflex, which causes the mother's breasts to expel milk. Lansinoh Ultra Absorbent Nursing Pads will ensure that mothers feel protected, ensuring their breasts stay dry, day and night. These absorbent nursing pads always stay dry by collecting any breast milk left on the skin and directing it to the core of the pad, where a special super-absorbent polymer captures moisture, capable of holding 20 times its weight and preventing leaks. Two non-slip adhesive strips keep the pad in place. Its contour fits naturally to the breast, so it won't show under clothing or leak. Advantages of Lansinoh nursing pads: Easily carried in your purse and individually wrapped for greater hygiene. Breathable and with a soft woven lining for maximum comfort. Great fit and absorbency to ensure skin stays dry and protected day and night. Leak-proof Blue Lock Nursing Pads.
