Brands of Small Toddler Underwear

Komfi Baby - Organic Cotton Underwear

Komfi Baby offers organic cotton underwear for babies and toddlers. They have both briefs and boxer styles. As the name suggests, these small underwear are super comfortable!

Even my newborn baby was able to wear Komfi Baby underwear while practicing elimination communication!

My daughter wore Komfi Baby girl's briefs into toddlerhood and I was really sad when she outgrew 2T/3T. It was hard to find anything with comparable quality and fit. Now they've extended the sizing to 4T/5T!

Highly recommended!

Noble Bebe - Preflat Diapers + Big Kid Undies

Noble Bebe Underwear or Training Pants
Noble Bebe Two Layer Toddler Kids Underwear

Noble Bebe is known for their brightly colored preflat cloth diapers. Reina uses the same stretchy bamboo French terry fabric for sewing big kid underwear. They have a unique design, with two separate layers. This allows you to add absorbency between the layers. So they can be used as absorbent cloth training pants and then regular underwear.

I loved that the design allowed me to use these as training pants, while still being easy to wash. But at the same time I wished the layers were sewn together around the leg bands. I would prefer a pocket opening at the back to allow for adding absorbency.

These were super comfortable and cute. I just wish my son hadn't outgrown them so quickly! I think they shrank with washing on hot. Be sure to measure your child and check the size chart.

 

Sizes: 18M - Kids 12 (My son outgrew size 18M by 12-months-old.)

Fabric: Stretchy bamboo rayon French terry

Shipping: Ships from USA

Made in: USA

City Threads Underwear - Made in the USA

City Threads is one of my favorite brands of toddler underwear for boys. I'm not as much of a fan of the girl's briefs. The boys underwear are available as either briefs or boxers.

These 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.

Fabric: 100% Cotton, or 100% Organic cotton

I recently found the Little Lupine Company Etsy shop! I hope to try these adorable organic cotton underwear on my youngest child once he is ready for underwear. I love the ocean inspired prints.
