How to Choose a Nursing Bra Size

Nursing bras provide a discreet and convenient way for breast-feeding mothers to nurse their babies while providing the support that their breasts require. Nursing bras come in several colors, with the most common being white, black, and nude. These bras may have different opening styles to give a mother quick, one-handed access to the breast while she holds her baby. The difficulty comes from knowing how to choose a nursing bra size and style that is efficient and easy for you to use.

Steps

  1. How.com.vn English: Step 1 Buy nursing bras at the end of your pregnancy or 1 to 2 weeks after the birth of your baby.
    The size of your breasts will vary greatly as your milk production adjusts to the demands of your baby, but they will usually level out in size by the second week.
  2. How.com.vn English: Step 2 Use a flexible measuring tape to measure around your torso, just under the breasts and under the arms.
    This is the first number in a bra size and indicates the band width. Add 3 inches (7.6 cm) to this measurement for the correct bandwidth for you. If the number is odd, choose the next highest even number.

  3. How.com.vn English: Step 3 Use the measuring tape to measure around your back and the fullest point across your breasts.
    Keep the tape in the back even with the tape in the front to get an accurate measurement.
    • The bra sizes are as followed: Cup A = 0 to 1.5-inch difference, B (1.5 to 2.5), C (2.5 to 3.5), D (3.5 to 4.5), E or DD (5 to 6), F or DDD (6 to 7), G (7 to 8), H (8 to 9), I (10), and J (10 to 11).
  4. How.com.vn English: Step 4 Use an online bra size calculator to help you determine the nursing bra size.
    • If you can, go to a mother-to-be store and try on as many styles as possible before making an online nursing bra purchase.
    • If you're buying nursing bras online, carefully follow the directions for measuring bra size from each manufacturer as it may differ from other stores. You want to obtain the best fit possible.
  5. How.com.vn English: Step 5 Buy nursing bras with wide straps.
    The wide straps help to distribute the weight of your breasts and provide more comfort.
  6. How.com.vn English: Step 6 Purchase nursing bras made of breathable materials such as cotton or synthetics that allow maximum air flow.
    Non-breathable materials will trap moisture next to the breast and encourage bacterial growth and soreness.
  7. How.com.vn English: Step 7 Choose a nursing bra with flaps that open and close easily with one hand.
    • Avoid bras that expose the breast entirely when opened, especially if you will need to feed the baby in public occasionally. These types of bras make it difficult to be discreet, although they may be used in private without much difficulty.
  8. How.com.vn English: Step 8 Buy at least 3 bras.
    Wait, however, until you find a style that is entirely comfortable and convenient for you to use.
  9. How.com.vn English: Step 9 Buy nursing bras that provide support under the breast while the nursing flaps are open.
    • Avoid bras with underwire unless you absolutely must have the extra support. Underwire bras can block the milk ducts in the breast, cause the milk ducts to become infected, and lead to mastitis.
