The innovative cut-out shape, which comes in sizes 16, 20, or 24 millimeters, allows the baby’s nose to make contact with his or her mother’s skin. Measure in millimeters, then add about 4 mm to this measurement—this allows for nipple expansion while your baby sucks. In some specific situations, the use of a nipple shield for a short period of time may provide some relief and support in the early days.

Using nipple shields can have negative consequences on breastfeeding, so they are only recommended in specific situations,’ Dr Lee says. Nipples may also become sore as they are constantly becoming wet and dry, due to frequent feeds and sometimes leaking milk. When you do try to wean your baby off the shield, it may be easier mid-feed, when your baby is less hungry, a bit sleepy and receptive to change,’ she says.Silicone is a great material for a nipple shield as it’s water-resistant and flexible, allowing the shield to fit perfectly and comfortably.

When a baby has a tongue-tie, they may not be able to open their mouth wide enough to get the whole areola into their mouth,’ says Dr Lee. Instead of using nipple shields, you may prefer to try a contact shield, which has a cutaway portion to allow the baby’s cheek to rest against the breast. Because the nipple is covered over, it is shielded from possible trauma as the baby latches on and starts to suck,’ she adds. For a baby to breastfeed properly, they must be correctly positioned at the breast, and have correct attachment, with the whole nipple in their mouth, including the areola, says Dr Lee.

In fact, many new moms use nipple shields during the early days after birth to help with soreness and feeding. As the baby sucks on the nipple, they push the nipple against the hard palate, squeezing milk out of the ducts, and swallowing,’ she explains. Some babies have a hard time latching beyond the nipple portion of the shield, particularly if it’s too big.
