-Place your thumbs on the base of the shield.
-Flip the shield halfway inside out. That’ll leave a small dimple at the end.
-Put your nipple into that dimple. Then, stretch the silicone base of the nipple shield down over your areola.
-Apply nipple cream or water around the edge of the nipple shield to help it stick.
