My toddler adores Thomas and, by extension, these underwear. They seemed scratchy to me but apparently they're soft enough that he doesn't seem irritated by the fabric. They're tagless except for a tiny little tag off to the side on the back that I snipped off. There's even an opening in the front -- totally useless but cute detail. Seem well made and ought to last (until they become too small in a short while -- they seem to run a bit small...at 2.5 y.o. and fairly slim, these fit snug).

My son loved these underwear. He obviously liked the pattern and design. He said they were comfortable. They held up in the wash and seem like good quality. They were more thick and not super thin like some. I would recommend!

My son just turned two and is in LOVE with Thomas. He's currently wearing pampers baby dry size 5 and the 2T/3T briefs fit him perfectly (he's 28 lbs, 33 inches tall). I can see these easily being too small on some other two year olds though. My son is pretty small except for his big 'ol toddler belly. These fit him nicely though and the images and colors are great. We washed and dried them before wearing as well. His new briefs have really helped start the potty training process. Even if he's not in the mood to go to the bathroom on the potty he still wants to wear these OVER his diaper or pull up! He knows he shouldn't pee on Thomas, so if he doesn't want to to the bathroom on the potty he'll ask for a diaper!

I bought the 2T undies for my kiddo who is consistently wearing 2T clothing. I had so much trouble finding undies small enough for his tiny bottom that I didn't buy a size up, like I usually do. I kind of wish I had. I was warned by other reviewers that these run a little small, which is true. These fit him just about right and are maybe a tad snug around the legs. If I'd bought 3T, I'd know we could get some future wear out of them. My only complaint is that the elastic is poor quality and a little stiff. I imagine that it doesn't feel good to have stiff, scratchy elastic around the inside of his thighs, though I haven't seen any signs of chafing. He loves the pattern and often wants to get them out of his drawer to look at the trains. It's hard to deny how cute little boys in undies are.

This is good cheap underwear for those potty training stages. No, it is not super soft organic cotton, but it has fun characters (we have 3 different character sets) and my son loves picking out his underwear ("Mickey!" "Goofy!"). For the price, you can stock up on 3 packets and have plenty of extras for diaper bags, etc. It’s the best you can get for the price. We looked around a lot and amazon has the best pricing as with many other items. This specific brand has other cartoons as well so buy a few that your child likes and give them options daily of what to wear. Important note: this product seems to shrink a little with washings as any other cotton item. We wash on warm and dry on low. My son wears 2T pants but wears 4T underwear. When he was in 18-24-month pants, he was wearing the 2T/3T underwear. So just be aware of shrinkage. His always recommend fun underwear for potty training purposes. Purchase all characters your child loves so they look forward to wearing underwear. They will get very excited to wear it if they love a certain cartoon. We first started our son at around 30 months but it was a little too soon so we will try again in a few months.

My little brother is obsessed with Thomas the train so these were a huge hit for a difficult to potty train boy! He proudly wore them daily and then didn’t have as many accident because he didn’t want to “ruin his trains†super smart move on my part! There wasn’t much stretch to them I thought but the sizing was accurate so it was no problem! They are easy to wash in case of accidents too. Definitely recommend.

Pensé que le quedarÃan un poco más grandes, le quedan justos, compren una talla mayor a la de sus niños, ajustan muy bien y el diseño es muy bonito además son de algodón
