1. Nursing Bra

Before you break the bank buying up sizes in your bra size, go ahead and invest in a few nursing bras that you can also wear after the baby is born. The advantage of a good nursing bra is that even if you don't plan to nurse, or nurse for very long, it can still be of use after the baby as your breasts go back to their regular size. Nursing bras are made with more stretch than your average bra and can often accommodate a range of cup sizes. Bravado's Original Nursing Bra fits a range of up to 4 different band and 2 cup sizes for each of their bra sizes. Also, well made nursing bras are more gentle on the breast tissue which is a great comfort factor to pregnant or nursing breasts as well as a health factor in reducing the risk of mastitis from a too-tight or badly fitting bra. Even the underwire nursing bras are often made with more padding and gentle wires than your standard wired bra. Melinda G makes a particularly gentle and supportive T-shirt Underwire Bra.

2. Maternity Jeans
