Why three is the practical minimum

Nursing bras get wet. Leaks, spilled milk and a baby being sick mean a bra can need changing more than once a day in the early weeks. One on, one in the wash and one drying is the smallest number that keeps you in a clean, dry bra. A fourth gives some slack when the washing does not get done.

Why buy in stages

Your size changes through these months. Breasts are typically at their fullest in the first weeks, while the ribcage is still wide from pregnancy. By around six to eight weeks, supply has usually settled, the breasts are often a little smaller than at their peak, and the band has come down. Bras bought to fit week one are frequently too big in the cup or band by week eight.

So start small, and buy the bulk when you know your settled size. The timing is laid out in when to buy nursing bras.

Frequently asked questions

How many nursing bras do I need?

Three is a workable minimum: one to wear, one in the wash and one spare. Most people settle on three or four daytime nursing bras plus one or two sleep bras.

How many nursing bras should I pack in my hospital bag?

Two soft, non-wired ones, plus breast pads. You are unlikely to need more for a short stay, and your size will change in the days after birth.

Do I need different bras for day and night?

Not necessarily. Many people like a soft, stretchy sleep bra at night to hold breast pads in place and give light support, and a more structured bra for the day.
