The pattern
For mothers with recurring clogged ducts and mastitis, it rarely feels like a surprise. It feels like a pattern.
-
Early symptoms begin
The tender spot, the heat, the ache — before the fever arrives.
-
You try everything again... and again
Hot showers, compresses, ibuprofen, hand expression at 2am. Over and over.
-
Yet, it still escalates to mastitis
Inflammation, bad cold, high fevers, and more antibiotics.
Wear it. Forget it. Feel better.
How it works
Why it works this way.
The massaging modules run one automated session at a time, easing discomfort and supporting lymphatic flow while you wear the bra you were going to wear anyway.
It's the same kind of gentle lymphatic massage a lactation consultant would walk you through by hand — just automated, so it actually gets done.

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.
-
Class I, FDA-registered
The device is registered and listed with the FDA. Registration and listing are not FDA approval or clearance.
-
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.
One mother in our discovery interviews described episodes coming back across roughly a year of breastfeeding: through the newborn weeks, again when her baby started solids, and again through weaning.
The difference
Same routine, minus the wrestling.
| By hand | With Sunday | |
|---|---|---|
| Hands needed | Both of them, for the whole session | None |
| When it happens | Whenever you can carve out the time | While you are already sitting down |
| What you track | Angle, pressure, direction, how long | Put it on and let it run |
| Afterwards | Compresses, towels, back to the sink | Modules out, garment in the wash |
In their words
What mothers told us.
From our discovery interviews and, soon, from people using it.

“I just kept showing up at the walk-in and saying, ‘I got mastitis again.’”

Questions
The things people ask us first.
Yes — it is designed to be worn as your everyday nursing bra, and it is compatible with both nursing and pumping. The massaging modules run one session at a time and are meant to ease discomfort and support lymphatic flow. As with any wearable, stop using it if something feels wrong, and check with your own clinician or lactation consultant if you are unsure.
The electronics lift out and the garment goes in the wash. The two massaging modules and the battery are removable, so there is nothing you have to hand-clean around.
TODO — how sizing is chosen at checkout, the range available, and what happens if the fit is wrong.
No. Sunday is a Class I 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.
