Unlike regular bras, maternity bras are designed to accommodate your enlarging breasts, your expanding rib cage and the increased strain on your chest muscles, so you don't want to just buy a regular bra in a few sizes up. A supportive, super-soft, full-coverage bra and a molded wireless cup bra are essentials that can be worn during pregnancy and after for nursing. Motherhood Maternity’s full coverage nursing bra and wireless nursing bra are great, affordable options. A sleep bra can help reduce back pain and maintain a natural lift. For active, nursing mamas, opt for a nursing sports bra with a pull-down or clip-down feature. I personally love the Beyond the Bump by Beyond Yoga sports bra. If you’re unsure of what size you need, visit a specialty store, like Motherhood Maternity® or A Pea in the Pod®, for a complimentary fitting. Their associates are expertly trained to ensure you have a proper fit.
