Tyr Buddy: Pull-Ups are only sized to 40lbs. I know there are kids who are more than that and still say they wear Pull-Ups. I should have known that for sizing. They would not work too well at your weight. Do you know any boys who might be using Pull-Ups? That sometimes happens. There are others(Depends and Attends) I think come in larger sizes for youth. I do not know about them, but maybe I am going to learn. Try the internet for links to Diapers. You should get info about both Disposable and Re-useable diapers.You might think about Re-useable diapers(cloth) if you get to the point that you would really need them. There are cloth Pull-Ons as well and they do come in appropriate sizes. It takes awhile to get them though. Let me know, Tyr, if we need to go further with this and do let me know later on how you are doing. Ask your mom to help you locate what we are talking about.
