Bought these for my 16 month old. She is 23 lbs and they fit her great, not tight at all and she will be able to wear them for awhile! They also appear to be comfortable, stretchy enough that she can move around in them easily. I don’t typically put her in jeans because they are stiff sometimes but these are great, especially for this price! I like them so much I bought them in the next size up too!
