Underwire Bras Are Safe for Nursing Moms.
The concern about wearing an underwire bra while nursing stems from the idea that the wire could inhibit blood flow and hamper milk production or lead to a clogged duct or even mastitis.
However, there’s no real evidence that underwire bras are linked to lactation problems.
When can I wear a nursing bra with underwire?
Is underwire safe during breastfeeding? Breastfeeding experts often recommend bras without underwire for the first 4-6 weeks of your breastfeeding, because milk ducts also lie underneath where the wire sits.
Can underwire bras decrease milk supply?
No coffee, no chocolate, no junk food — and according to many websites and lactation consultants, no underwire bras. Underwire bras, experts said, could block the natural flow of breast milk, thus decreasing milk supply in the long run.
Can you wear an underwire bra while pregnant?
Yes. Wearing an underwire bra while you’re pregnant shouldn’t cause a health problem for you or your baby. And there’s no evidence that underwire bras and lactation problems are linked. That said, many women opt for wire-free bras by the second or third trimester simply because they find them more comfortable.
