Tiny Undies - small baby underwear, 3-pack

Regular price $30.00 $25.00 Sale



Dress your tiny bottomed baby or toddler in the Tiny Undies unisex Bold Color Collection.

Each package contains 3 pair of one size tiny baby or toddler underwear: 100% cotton, all natural, sweatshop-free.

  • Made of super-soft 100% OEKO-TEX 100 Certified cotton with eco-friendly dyes on colored styles (natural color is undyed/unbleached), these undies are BCSI-Certified sweatshop-free and free from harmful chemicals.
  • Great for potty training and elimination communication, Tiny Undies have a single-layer crotch with no padding…training pants feel a lot like diapers to 2 and 3 year olds, so skip them and go straight to undies! (If you have a younger child, training pants can be helpful!)
  • Low-rise, anatomically-correct fit for babies, young toddlers, and older toddlers who typically have a tiny waist and protruding belly; tag-free and itch-free.
  • Unisex design and colors make them reusable for multiple children (and solid colors make it easy to spot wetness); waistband and leg gussets are thick and soft, making them easy to pull up and down, and comfortable to wear all the time; see size chart in images for correct fit.
  • Mama-owned small company in the USA (Andrea is an Elimination Communication and potty training expert here in North Carolina).

Great customer service

Please be aware if your tiny has bigger thighs…. Size up…. I did. But I should go 2 sizes bigger. So just be aware and ask customer service before ordering

The best undies

My son has been wearing Tiny Undies for a few years, and we love them. Excellent quality (they never wear out or stretch out) and fit (my son is very skinny and they fit true to size). I can’t recommend them enough!
