The set includes an inner shell (24 mm) and three additional insert sizes (17,19 and 21 mm). A well-fitting inner shell is important for comfortable and efficient expressing. To find the right size, measure the size of your nipple. The nipple determines the size of the inner shell, and not the size of your breast. Measuring your nipple is very simple. Use a tape measure or ruler to measure the diameter of the nipple at the base, excluding the areola. No two breasts are the same, so you may need different sizes for each of your breasts. Therefore, you should measure the nipples of both breasts.
Take note of the following
- The nipple should be able to move freely within the shell.
- Make sure the areola is not pulled into the breast shield.
- When you fit the shield, 1-2 mm of space around the nipple is normal.
- A shield that is too large or too small can lead to pain, damaged skin and poor production.
- Never express milk for longer than 30 minutes.
