I loved them so much that I went back and bought another set, totaling 12, which is a great amount for potty training."

"I was in search of thicker underwear for my potty-trained 18-month-old, looking for something with extra padding for public outings. While these are absorbent enough for minor messes, they didn't prevent leaks when I carried him.

He enjoys wearing them, and they are comfortable without being bulky. Overall, a great product that meets my expectations!"

"After washing and drying these right away, I found them to be of great quality. They are incredibly soft for my son, and I appreciate the covered elastic, making it gentler around his waist. At 2 1/2 years old and 25 lbs, he fits into them with some room to grow. The padding is just right, catching minor accidents effectively—perfect for his potty training stage!"

"I’m editing my review on the training pants because they genuinely work well. I've had great experiences with Gerber pants—they're thick and absorbent, catching most messes.

While I'm currently frustrated, I still have faith in the product itself since I loved them for my previous kids."
