I had the same problem. My daughter is turning four soon and is just fitting into the smallest (2T) underwear we can find. I had a friend who sews custom make some for us when Rachel was just starting potty training because we couldn't find any small enough.

It's funny that I saw this post today of all days. We started potty training today! Holly is also super tiny - she's 2.5 yrs old and 19 lbs with not much of a bum. We searched high and low, and posted here as well for ideas. We're limited to shopping in Canada - it was too expensive with the exchange and shipping. The smallest ones we found locally were the George brand at Wal-mart, recommended by someone on this forum. And even then, a friend of mine who sews took them in for us.

Good luck with your search and with potty training!

My daughter is really small and when I was potty training her she couldn't fit into big girl underwear but I found 18/24 mth cloth training pants at Walmart in Canada anyway. I don't know if they carry them in the US though. Someone else mentioned the Gap and that is a good idea as well. Good luck in your search.

I bought the smallest size and then washed and dried them a few times to shrink them. It's funny to remember that! Hannah now wears big girl sizes and we have no problem with them fitting now :)

Baby gap has XS sizes, when shrunk that worked for my little one. She was also 12 months behind in clothing sizes. And it's ok if they are a little baggie....helps give their pants something so they don't slide off.

Walmart has Elmo and Mickey Mouse Clubhouse underwear that actually run quite small. My son just turned 4, he is 30 lbs, and I finally got to throw those tiny unders out. They are sold in the baby section. They are much smaller than like the Furit of the Loom or Hanes. Aiden started wearing them when he was 2, and he was only 20 lbs at 2.

Mason is so tiny and his 12 month stuff is still too big around the waist, he is long and lean too! I bought some Elmo underwear from Target that came in, I think, a 5 or 6 pack and they are SO tiny. The size is 2T but I think they start at 20lbs. So far Mason is still scared of the potty and we are thinking we will have to wait a few months until he is 2 1/2 but I do have underwear when that day comes :) I looked all around and these underwear started at the lowest weight of any that I found. If you are looking for cloth training pants, I was able to find 18 month size at Babies R Us by Gerber. I hope you have some luck!

I don't know if you'll find some quite that small, but I know that some people have had good luck with Hanna Andersson.

I've not seen them smaller than 2T/3T in any store like Target.

We tried and failed miserably a few weeks ago with Alexander. He is very skinny too (maybe not as skinny as logan though) and the 2T from Hanes fit him OK. The other ones (Fruit of the Loom maybe) ran bigger and didn't fit as well.

Good luck potty training!

so this is an interesting little dilemma im having. my son who is almost two is showing definite readiness to start potty training. however he is still very small for his age, with a waist about the size of a 9 month old, he is long and lean. and i cant find underwear anywhere that are smaller than 2T. did anyone else have a similar problem and know where i can find some smaller underwear?
