ペドロ ボン 5 For my 3 years son it is perfect. The waist’s size is also good. It is being helping me a lot since all the pee that was leaking now is being absorbed. Of course, it also depends on how much liquid my son drank and if he went to toilet before sleep or not.But it is better than before, now instead of the bed being only him is getting wet.The biggest problem is to dry when we do not have sun. It takes time.
