Small Toddler Underwear for Potty Training and EC Grads

Are you searching for small toddler underwear for potty training or for your elimination communication graduate? We've got you covered! Whether you are looking for the smallest toddler underwear or organic toddler underwear, we have recommendations for you. Our list below includes boys briefs, boys boxers, and girls undies. There are brands of extra small underwear for petite toddlers, starting from sizes 18 months, 12 months, and even baby underwear from size 6 months!

If you are following the Tiny Potty Training Book, your toddler will start out bare-bottomed during the initial teaching phase. Then your toddler can go commando for a week or two. Once the pottying routine is going well, it's time to introduce underwear.

If your toddler is practicing elimination communication and only having a couple misses per day you can try transitioning to underwear. Other indications that it's time to take the leap include your toddler signalling the need to potty or your toddler occasionally going to the bathroom on his own.

Brands of Small Toddler Underwear

City Threads™ Toddler Underwear - Made in USA

City Threads is one of our favorite brands of toddler underwear! We like that City Threads underwear are high quality and made in the USA. You can choose from thick 100% cotton or 100% organic cotton.

Size 18-24M fit my petite son from the time he was 2-years-old until he was 3-years-old.

We have the boys briefs, but you can also choose from boys boxer briefs, unisex briefs, or girl's dance shorts. The dance shorts would be perfect for wearing under a skirt or dress.

H&M Toddler Underwear

H&M toddler underwear is another option if you are looking for boys or girls boxer briefs. Their conscious collection is made with organic cotton. The waistband on the H&M size 1.5-2yrs boys boxer shorts finally fit my thin son once he was 3-years-old. The waistband on the boys boxers is exposed elastic, so they may not be the best choice if your son has super sensitive skin.

Tiny Undies™ for Babies and Toddlers

Tiny Undies offers 100% cotton extra small toddler underwear and baby under pants starting from size 6 months. Tiny Undies are designed by Andrea Olson, author of Go Diaper Free: A Simple Handbook for Elimination Communication and The Tiny Potty Training Book.

The LEARN collection by Tiny Undies helps promote self dressing. We are trying them out right now, to see if they will help my toddler want to dress himself in the morning. Tiny undies are also available in bold gender-neutral solids and prints.

Tiny Undies now also offers super small boxer underwear! These are designed to be gender-neutral, so they can be worn by a boy or a girl.
