Nursing bras
Your breasts change in the first trimester and again when your milk comes in after the birth. So a nursing bra shouldn’t be tight or “exact to the millimetre”. It should support, and not dig in.
Why the bra matters so much
Tender, bigger breasts are among the first signs of pregnancy.1 After the birth your size changes again: the breasts often fill up about two to four days after the birth, when your milk “comes in”.2 And through the day it changes depending on when your baby last fed.
For breastfeeding, what matters is that the bra doesn’t dig in. The NHS recommends a well-fitting bra that doesn’t squash the breasts,3 and lists pressure from a tight bra among the possible causes of a blocked milk duct.4 With mastitis, it advises not wearing tight bras and clothing until things improve.5
Types of bra
| Type | How you breastfeed | Who it suits |
|---|---|---|
| Drop-cup with a clip on the strap | you unclip it and the cup drops down | the most common; check that you can manage the clip one-handed |
| Crossover | you pull the cup aside | soft, no clips, often good for sleeping too |
| Soft sports-style with drop cups | you drop the cup or pull it aside | support when active and for a bigger bust |
| Maternity bra without nursing access | you can’t breastfeed without taking it off | for pregnancy only; consider a nursing bra instead |
When to buy
- In pregnancy: when your usual bra starts to feel tight. Go for a soft, adjustable one, ideally already a nursing bra.
- For the maternity hospital: the NHS recommends packing two or three comfortable bras, and nursing bras if you plan to breastfeed.6
- Once things settle: buy the rest once your size has settled after your milk comes in. The first weeks tend to be the most changeable.
How it should fit
- the band holds but doesn’t cut in; after the birth the loosest hook may be useful,
- the cup covers the breast without wrinkling and without the breast spilling out at the top or sides,
- nothing presses on the side of the breast or into the armpit,
- there is room in the cup for a breast pad,
- you can open the cup with one hand.
If you feel pressure, or see a red mark, the bra is too tight.
How many
Two or three nursing bras are enough to start with: one on, one in the wash, one for the night. Add more once you know which type suits you.
When your breast hurts
A bra is not a treatment. If you have a painful, hard or red area, a fever, or you feel as though you have flu, get in touch with your doctor, midwife or a lactation consultant (laktačná poradkyňa). You will find the basics of getting started with breastfeeding in the guide Breastfeeding – the first weeks.
Frequently asked questions
Does a nursing bra have to be non-wired?
The sources we rely on talk not about underwires but about pressure. The NHS recommends a bra that doesn’t squash the breasts, and lists a tight bra among the possible causes of a blocked milk duct. Soft non-wired styles adapt more easily to your changing size, which is why many women choose them, especially in the first weeks.
Can I sleep in a bra?
If it suits you, yes. At night a soft, looser bra or a vest that holds breast pads in place works well. Nothing should dig in.
