After Birth Underwear: What You Need To Know

Bringing a baby into the world is beautiful... and messy. Between the joy, sleep deprivation, and hormone rollercoaster, there’s a lot going on. One often-overlooked item that really matters after birth? Underwear.

Yup, we’re talking about postpartum undies. One specific question we get asked time and time again: how many postpartum underwear do I need? If you're staring at your hospital bag wondering how many pairs to pack, you’re in the right place. Let’s break it all down.

Why Postpartum Underwear Matters

Postpartum bleeding (also called lochia) can last for up to 6 weeks. That means your regular underwear just won’t cut it. You need something that’s comfy, supportive, leak-proof, and breathable. Bonus points if it doesn’t make you feel like you’re wearing a giant diaper.

That’s where specially designed postpartum underwear comes in. Think: high-waisted underwear that hugs your belly, soft fabrics that won’t irritate c-section scars or sensitive skin, and built-in absorbency that keeps leaks at bay. If you’re healing from a vaginal birth, comfort and flexibility are everything.

How Many Postpartum Underwear Do I Need?

The sweet spot is usually 5 to 7 pairs of reusable postpartum underwear. Why?

  • You’ll likely bleed or leak for several weeks.
  • Laundry may not be top priority with a newborn (understandably!).
  • Accidents happen, and it’s good to have backups.

Here’s a quick breakdown:

  • Hospital Bag: Pack 2-3 pairs for the hospital stay.
  • At Home: Keep 3-4 more at home so you can rotate.

 

If you’re using disposable mesh underwear initially (which many hospitals provide), you can start transitioning to reusable styles like Fri Period’s Classic Briefs within a few days.

How Many Disposable Underwear After Birth?

If you’re going the disposable route in the early days, expect to use 1-2 pairs per day for the first 3-5 days. So having a pack of 10-12 disposable postpartum underwear is usually plenty.

That’s especially true if you’re dealing with heavier postpartum bleeding or still managing healing wounds.

But keep in mind, disposable = waste. They’re convenient, sure, but not great for the planet. That’s why many new mamas are opting for reusable underwear that’s just as convenient (and way more sustainable).

Reusable vs. Disposable: What’s Best?

Honestly? Reusable wins in almost every category. Especially when you're wearing them 24/7.

When To Start Wearing Reusable Postpartum Underwear

You can start wearing reusable leak-proof underwear as soon as you feel ready — even during those first days at home. Brands like Fri Period are designed to handle heavy flow and function like absorbent underwear, so you don’t have to wait weeks.

Got stitches or a sensitive tummy? Opt for soft, high-rise options like the Boxer Brief, which provide light compression underwear benefits and gentle support.

Washing & Caring For Them

Reusable doesn’t mean complicated. Here’s how to keep them fresh:

  1. Rinse in cold water after use.
  2. Toss in a delicates bag and machine wash cold.
  3. Line dry to keep them in tip-top shape.

Tip: Have a wash bag handy for tossing used pairs in until laundry day. Always follow the care instructions to preserve fabric quality.

Packing Your Postpartum Wardrobe

Besides postpartum underwear, here’s what else you might want:

  • Nursing bras or tanks
  • Loose-fitting clothes or robes
  • Maternity or postpartum pads (if needed)
  • Breast pads (for leaks up top)
  • Ice packs for extra cooling comfort

Think of it like prepping for comfort, not a fashion show. Add a few hospital bag essentials and you're ready to go.

Final Thoughts

So, how many postpartum underwear do you need? Around 5 to 7 pairs if you’re going reusable. If you’re using disposable postpartum underwear, aim for 10-12 to cover those early days. Then make the switch to something comfier, more supportive, and way better for the environment.

Your postpartum journey deserves softness, sustainability, and zero stress about leaks. Fri Period has you covered (literally) with breathable, organic cotton styles that feel like a warm hug when you need it most.
