With the following list, a lactating woman can easily assess whether she is using the correct breastshield / flange size:
If you already have an electric breast pump you can try the following. Center your nipple in the tunnel of the breastshield / flange. Now begin pumping and check the following points:
- Is your nipple moving freely in the tunnel?
- Is none or only very little tissue of the areola being pulled into the tunnel of the breastshield?
- Do you recognize gentle, rhythmic movements in the breast at each pump cycle?
- Do you feel the breast emptying all over?
- Is your nipple free of pain?
If the answer to any of the above questions is "No", please select a bigger (or smaller) breastshield / flange.
Correctly fitted breastshields are important

Improperly fitting breastshields
The amount of distance between the tunnel wall and your nipple should only be a couple of millimeters so that none of the areola skin actually goes into the shield.

Many woman are usually using a shield size to BIG rather than too small. Although we highly recommend the Medela breast pump and its accessories like the "PersonalFit" breastshields / flanges, you should be aware of the sizes in which you can choose. This is usually universal if a pump has removable or custom fitting flanges / shields, they will, more than likely, be in these sizes:
