A nursing bra labeled as a “sleeping” bra is specially designed to be worn during sleeping. It can also be worn when simply lounging around the house, during naps, and resting periods. The material is often much softer and more pliable than day-wear bras, and may not provide as much support. However, they are meant to be extremely comfortable and easy to use in case you need to nurse your baby during a midnight session. A sleeping bra is still equipped with detachable fasteners or removable cups, so you won’t be losing any of those benefits. You can often find sleeping bras constructed of jersey fabric, which is a common material in sleepwear.
