A flexiwire is on the underside of the nursing bra cup and provides shape and structure to the cup. It differs from a traditional underwire bra in that it is soft and flexible and is designed to flex as your breasts increase and decrease in size.
Concerns about wearing an underwire bra while nursing stems from the idea that the rigidity of the wire could inhibit blood flow and hamper milk production or lead to a clogged duct or even mastitis. However there is no real evidence that (correctly fitted) underwire bras are linked to lactation problems. The issue is more that many women are clearly wearing the wrong sized bra.
Hotmilk have developed a range of products with a metal flexiwire support for the following reasons:
1. Flexiwire support holds the shape of the cup and supports rather than flattens
and compresses the bust.
2. Flexiwire support is better at holding the bra against the frame of the body for
increased cup and band support.
Excerpt from The Australian Breastfeeding Association:
"Many women prefer underwire fashion bras and are confused when told these are not recommended during pregnancy or lactation. The reason for this is, once again, your changing breast shape. When breastfeeding, the breasts can increase and decrease in size during the day, as milk is produced and removed. Retained fluid in late pregnancy can also cause the breast to swell. Although only a slight change in size is occurring, a rigid underwire may put pressure on the breast when it is fuller. Such pressure can lead to blocked milk ducts or mastitis and it is for this reason inflexible underwire bras are not recommended. However there are now nursing bras available that have a flexible metal support, similar to an underwire, designed to flex and change position with your changing shape. These are less likely to cause problems."
