THANK GOD someone makes normal underwear without cartoon characters for toddlers (of course you always have the tidy whities, but I'm not a fan of those)! My son just turned 3 (weighs 29lbs), and it's got a lot of stretch and give, even after washing. The length is just a little long, like a little short of halfway to his knees. It's not as tight as I thought it would be, but he can probably continue to wear them when he's 4, so it's a good purchase. They are just adorable and "just like Daddy's".
