For mothers who are all too familiar with the struggle
You shouldn't have to guess
what's coming next.
Sunday is a nursing bra with embedded massaging technology for mastitis, clogged duct, and milk production support. Designed to help you stay ahead of it.

The product
with callout labels:
modules, battery, clip
-
The one bra you actually need
Works for nursing and for pumping.
-
One session, start to finish
Roughly ten sessions from a single overnight charge.
-
Wash the bra, keep the tech dry
Modules are removable, the rest is machine-washable.
The pattern
Once you have had clogged ducts or mastitis more than once, it stops feeling like bad luck and starts feeling like a pattern you can see coming.
-
It starts the same way
A sore spot, a patch of heat, a dull ache — always before the fever.
-
You run the whole list again
Warm shower, cold compress, ibuprofen, hand expressing at two in the morning.
-
And it still becomes mastitis
Swelling, chills, a fever that climbs, another course of antibiotics.
Wear it. Forget it. Feel better.
How it works
Why it works this way.
The two massaging modules run one automated session at a time, easing discomfort and supporting milk flow. Put it on, and it gets done — which is the part that usually doesn’t.

What’s behind it
A physical therapist’s technique, run for you.
The two massaging modules follow a lymphatic drainage pattern designed by a physical therapist — the same technique a lactation consultant would walk you through by hand, in the same order and direction. The difference is that you don’t have to do it yourself.
-
Designed by a physical therapist
The drainage sequence isn’t improvised. It follows the same path a consultant teaches by hand.
-
Built from mothers’ accounts
We designed it around what mothers with recurring episodes were already being told to do, and how hard that is to actually do.
The difference
Same routine, minus the wrestling.
| By hand | With Sunday | |
|---|---|---|
| Hands needed | Both, for the whole session | With Sunday — None |
| How long it takes | As long as you can manage | With Sunday — One automated session |
| What you have to get right | Angle, pressure, direction, timing | With Sunday — Nothing — the same pattern every time |
| Where you have to be | At the sink or in the shower | With Sunday — Wherever you were already sitting |
| Clearing up after | Compresses, towels, back to the sink | With Sunday — Modules out, bra in the wash |
Early testers & specialists
What they told us.
-
“I was so tired of going to the urgent care walk-in every time I got symptoms. Now I can just turn the massage on at home.”
An early tester
-
“My patients come into the city to our clinic for this manual massage. I recommend this for them to use in between visits, or to keep going at home, because there isn’t always a time that works for them to come in.”

“Such a great addition to my maternity clothing collection — it’s like an at-home, on-demand massage when I’m getting some pain.”

Questions
The things people ask us first.
Yes. It’s built to be the nursing bra you were going to wear anyway, and it works for both nursing and pumping. The modules run a single session at a time, easing discomfort and supporting milk flow while you have it on. As with anything you wear, stop if something doesn’t feel right, and check with your clinician or lactation consultant if you’re unsure.
Take the two modules and the battery out — they lift straight out, so there’s nothing to clean around — and the bra goes in the wash. Wipe the modules with a damp cloth and don’t submerge them.
Sunday comes in XS through XL, and you choose your size at checkout. If you normally wear a nursing bra, order the size you already wear in that. If the fit isn’t right when it arrives, the 30-day return window covers it — send it back and we’ll sort out the right size.
No. Sunday is a device sold directly, so you can order it without a prescription or a referral. If you're already working with a lactation consultant or a provider, it's worth telling them you're using it so it fits alongside whatever else they've suggested.
You have 30 days from delivery to send it back for a full refund. Email us and we'll start the return — it can be used, and you don't need the original packaging.
Immediately. Orders leave us as they come in, and you'll get a confirmation right away and tracking as soon as your box is moving.
