In the early postpartum (and sometimes late pre-natal) period, women with
larger breasts often find themselves much more comfortable if they wear a
bra even at night.  If an average breast weighs 600 - 800 grams while
lactating, some of these women may be carrying around a couple of extra
kilograms!

I write from both personal and professional experience.  When I first began
my work, I assumed that everybody slept in a nursing bra for at least the
first month or two...  I was shocked when I worked with one small-breasted
woman who almost never wore a bra!  I learned that my job is to evaluate
each woman according to her needs, offering suggestions for comfort and
success.  Most large breasted women are really thankful to find a
comfortable  nursing bra for nightime!
