How do I pick the right size underwear for my child?

Just visit our Size Guide here to find the perfect size undies. If in doubt, contact us and we'll help you make your final selections.


Are your undies easy for my child to pull up/down?

Yes. The waistbands are designed with extra wide and comfortable cloth-covered elastic which makes them extremely easy to push down and pull up. Great for potty training and teaching this part of the pottying process (covered in-depth in Go Diaper Free).

Will your undies help my child self-dress?

If you want to teach your child easy self-dressing, consider ordering the Bear/LEARN pattern of Tiny Undies or Tiny Trainers - they are designed specifically to assist teaching this task.

When should I choose trainers vs. undies? What is the difference?

During EC, many parents use training pants during outings, nighttime, and daycare, and any other time you'd like to keep pants and surfaces more dry than undies alone will keep them. Tiny Trainers have a double-layer of needle-punched cotton that will usually absorb a small to medium sized pee, but pants will probably still get wet. (Normally, though, trainers will keep the floor from becoming wet.) Most other brands of training pants do not offer this much absorbency. Learn more in Go Diaper Free.

For potty training with a 2 or 3 year old, you might find it works better going straight from diapers to undies (as opposed to training pants), simply because the undies have the least absorbancy and therefore are the least diaper-like (to help reinforce the potty training process). However, you can also use training pants as a back-up during outings, nighttime, and daycare. Learn more in The Tiny Potty Training Book.

Bottom line? The main difference between my trainers and undies is absorbency. Tiny Trainers have a double layer of needle-punched cotton in the center as well as two layers of regular cotton. Tiny Undies are a single layer of regular cotton. The choice is up to you! If you need help with your decision, hit the chat button in the corner of this page or contact us here.

Are the colors going to match those on my screen?

Two things: 1. The resolution, contrast, and color display varies on all digital screens, so the color you see may not be an exact match. 2. Our undies/trainers are naturally-dyed, which has some dye variation inherent in the dyeing process. We try to control variations as much as possible but sometimes the color you receive may vary from what you see online. Thanks for understanding, and for enjoying what you receive…we love all of the colors and are sure you will, too!

Do your undies have extra padding in them?

No. They are a single layer of cotton. Please see our Tiny Trainers for a padded option.

Do your training pants need a cover?

See “When should I choose training pants?” above. Short answer: If you want to keep pants dry and your child is still having pee accidents or misses, you can cover Tiny Trainers with our TinyUps cloth pull-up covers. Tiny Trainers usually absorb a small- to medium-sized pee, but since they have no plastic or PUL layer, it’s possible the liquid can get onto the pants (and couch) as well. (Generally, the liquid does stay off the floor without a cover.) Your mileage may vary, and we offer lots of options to suit your style!

Will your products shrink?

Yes, they are 100% cotton, so you can expect up to 6% shrinkage. Please see our Care Instructions, below.

Do you use organic cotton?

We’re glad you asked! Our underwear and training pants are made from 100% natural cotton that is OEKO-TEX-100 certified. This certification is even more strict than most organic certifications. Our cotton fabric is also certified azo-dye-free. If you want to go even more natural, we offer an unbleached/undyed option in our undies and trainers.

Are your products made in the USA?

Great news: Our Top Hat Potties, Mini Potties, and Flushhush are now made in the USA! Practically just around the corner from us in Dalton, Georgia.

Presently, we are researching textile production here in the USA (and even considering opening our own cut and sew shop) to give you more variety and higher quality at the same inexpensive cost. Please stay tuned, and we’ll let you know all the exciting details. In the meanwhile, all products  currently for sale in our online shop were designed here in Asheville, North Carolina, and we took great care in selecting an eco-conscious, BSCI certified sweatshop-free textile manufacturer in China, employing mothers who earn a fair wage.


Can I buy your products in a physical store?

At this time, it makes more sense to only sell our products online. Someday soon, we'd love to expand to like-minded small shop owners  , and some of our Go Diaper Free coaches may have products available to purchase. Generally, though, they are not found in stores near you to keep our small, mama-run business sustainable.

Do you offer bulk discounts or wholesale pricing?

Only on a case-by-case basis. Please see our Wholesale Terms and Conditions and complete our Tiny Undies Wholesale Application to be considered.

Can I buy less than/more than 3 pair on an individual basis, a mixed color package, or patterns?

At this time we only offer 3-packs of a single color. We occasionally offer a limited-time pattern or a mixed-color package to celebrate a holiday. Those are special occasions, and as rule, we keep our underwear gender-neutral and solid-colored by design.

How many pair of Undies/Trainers do I need?

This varies by child, of course, but a good start is 9-12 pairs for each child. This amounts to 3 or 4 of our 3-packs (and that quantity might just earn you free shipping, btw!). This will give you adequate stock to rotate if you have a lot of pee misses or accidents, and/or don’t get to your laundry immediately every single time.


Can I change my order prior to shipping?

In order to provide the best service to our customers we do not allow cancellations or changes after an order has been placed. Be sure to double-check sizes, colors, and quantity in your cart before you check out. (Please see “How do I pick the right size underwear for my child?” above for helpful sizing info, or reach out to us first if you need help.) See “Returns/Exchanges” for more details. 

What currency do you use for the price of your products?

The prices on the site are in US dollars.



Do you ship to (name a country)?

Yes! We will ship anywhere. (Provided there are no carrier or government restrictions outside of our control, please see below.) During checkout, you'll be able to preview your shipping charges prior to paying for your order. We ship all international orders via United States Postal Service or UPS. Please note, we are not responsible for any additional duties or customs fees charged to you by your carrier or destination country of certain international orders.

Some countries may require priority or express services. While we strive to ship anywhere, please review the shipping guidelines and any additional charges that may apply to your country. 

Do you offer free shipping?

Yes! We are offering free standard shipping on orders over $75 for domestic (US) shipping only. 

How long will it take to get my shipment?

We ship primarily via USPS (they are the fastest and most economical), with these guidelines:

First Class Mail is automatically selected unless your order is over 13oz, in which case it will be sent Priority Mail. First Class is the most economical option but in most instances will take slightly more time.

If you select to upgrade to Priority Mail, you will generally receive your items more quickly. 

We typically have orders packed and shipped out from our warehouse within 1-2 business days of receiving your order during normal periods.  Extra busy times such as Black Friday/Cyber Monday ship out within 7 business days. However, once a package is shipped out carrier delays may occur (ie: holidays, customs, etc). Thanks for understanding and supporting a small business!

Can I change my order after it is placed?

We are a small business with team members across the country who take customer service seriously! Unfortunately, our small team means that once an order is placed (sent to the warehouse for fulfillment), it is unable to be changed. 

If we make a mistake pulling your order, we want to make it right! However, if you want to change something about an order already placed, you will be responsible for covering shipping & handling costs of any unwanted items sent back to us for refund (subject to our return policy, below). To start an exchange click here.

How do you ship?

We currently ship via the United States Postal Service. They rock.

Can I track my shipment?

Of course! All shipments, domestic and international, are labeled with USPS tracking numbers. When your item ships, we send you an email with your unique tracking number in it. Open that email. Click the tracking number link that’s inside and you will go to the USPS website to see where your package is and when it is scheduled to arrive. Please note, typically, it takes 24-48 hours from the time we ship to when the tracking info is updated in the USPS tracking system.

Care Instructions

How do I care for my Tiny Undies and Tiny Trainers?

We recommend you wash on cold and tumble dry on a low or medium setting to reduce shrinkage, as at these young ages, every inch counts. Tiny Trainers will need one to three washes and dry cycles to properly “fluff” their absorbent core. Ironing is not necessary. If you are worried about potential shrinkage (currently, we’re noticing about 6%, which is standard for unshrunk cotton), you can size up one size.


How do I care for my TinyUps?

We recommend you wash your TinyUps with warm water (no dry cleaning) and tumble dry on a low or medium setting to reduce shrinkage. Do not bleach. Ironing is not necessary. If you have an ammonia smell that simply won't go away (this can happen depending on the strength of your child's urine), we recommend an online search for "stripping cloth diapers" to learn how to "strip" your covers of stinkiness.


What is your returns policy?

So we can give your situation the care it deserves, please do not ship anything back to us without using our returns app (below). Returns sent without prior authorization will not be accepted.

Items will only be considered for return or exchange if:

  • they are unwashed/unworn
  • within 30 days of delivery
  • any related packaging is un-altered/undamaged (damaged/altered packaging affects our ability to offer it for sale to another mama, so we are unable to accept these for return).

You may initiate a return/exchange request by clicking here.

For approved return/exchanges: We are a small shop with limited inventory and your return will likely end up in the hands of other mamas after we receive and inspect it, so please use care in packaging it to mail back to us! Products damaged in transit due to insufficient packaging will not be refunded.


Who pays shipping costs?

For approved returns/exchanges, shipping is free if the error is ours. Please initiate a return/exchange request by clicking here.

All clearance item sales are final, no returns/no exchanges. Thank you for your understanding!
