Are you searching for small toddler underwear? I know how challenging it can be to find small underwear for toddlers who:
- are small for their age;
- potty train before two-years-old;
- are elimination communication graduates; or
- complete Montessori toilet learning at a young age.
Babies practicing elimination communication may even be ready to start wearing underwear, for at least part of the day, at around 6-months-old.
I am here to help you in your search for extra small toddler underwear starting from 12 months or 18 months sizes or teeny tiny baby underwear. If you feel that your baby or toddler is ready to move on from diapers or training pants to panties or boxers, don't let the limited options hold you back. Below you can find the smallest toddler underwear for boys and girls as well as underwear for babies practicing elimination communication.
Our Search for Small Toddler Underwear
I started practicing elimination communication with my son when he was one-month-old and he switched from wearing cloth diapers to cloth training pants at 12-months-old. He is small for his age, and I knew that when the time came it would be difficult to find underwear that fit.
While traveling in Asia, I checked every super market, department store, and baby store for small underwear. Practicing EC and potty training before three-years-old is more common in Asia, so it is easier to find small potties and undies. Even so, I only found a couple places to buy itty bitty underwear. In Thailand I found Winnie the Pooh underwear at Tesco Lotus that fit my 20 pound 19-month-old. In Japan I found super cute briefs at Muji in size 90cm that fit him well and are high quality (pictured above). There are now some Muji stores in the USA, but at least the online store does not offer the smaller sizes of underwear. I wish we had purchased more than two pairs!
Once my son turned 24-months-old, and our traveling lifestyle settled down, we made the switch from cloth training pants to real underwear. We have tried most of the brands listed below.
