First i have tried finding this in other places and got no luck so here it goes. I recently got hold of some child diapers that only support 40 pounds. and i am kinda over that at 150 pounds so the waistbands don't reach by like 2 inches. So what i am wondering is if there is a way to get them to expand and reach so the can be put together. (as to wear them now i have to wear some tight underwear to support it against me) any suggestions would be nice

(and i know an easy solution is get bigger ones but this is all i could mange to find and they were free so they'll have to do
