When feeding period starts, breasts become bigger and more sensitive. Having the right nursing bra is a necessity; you should have more protection and support for your chest. There is a high chance of having your breasts grow bigger during the nursing period, so you need to shop wisely and plan ahead. You might want to get a bigger size than you are wearing now.
Look for the fabric that is silky, soft, and stretchy; this way it optimally adapts to the developing breasts and supports their shape.
