Encourage your letdown and increase your milk flow Babies can be super-efficient at extracting milk from the breast, however, sometimes they need a helping hand - or a breast shield in this case! The soft silicone breast shield is fitted comfortably, adapting to the shape of your breast, to create a powerful suction similar to your baby’s mouth. This helps to promote your letdown and optimises your milk flow to make every pumping session a rewarding one. One size doesn’t fit all We’ve designed our breast shields to come in a variety of sizes to accommodate all body shapes and sizes. Lola&Lykke breast shields are available in 21mm, 24mm, and 27mm so you can choose the right fit for you. Refer to the sizing chart to ensure you measure correctly. Safe for you and your baby We use BPA-free materials (silicone) in our products to ensure the safety of you and your baby. Only the best for you and your baby!
