My grandson is 18 months, so potty training is on the horizon. He is a big boy, wearing 24 month size clothing. I purchased these for him for Christmas, he will love the cute designs on them, and they are definitely all boy. Very well made, excellent quality. They’re going to be just a bit large on him, so I feel the sizes listed are accurate. One thing I found odd, the tags are on the outside. Attached just like a regular size tag, but sewn to the outside. Not a bad idea when you think about it, it won’t irritate their skin, but it just surprised me.
