Hi hon, I was thinking of you and this problem just the other day when I put some of DS's pants over a cushie tooshie and thought gosh it's a tight fit! So I did have to take them off and put a larger size on him. I don't have that problem at all with the ebay ones I bought. I know you have some of them too, maybe if he's only at home and there's something in particular that you want him to wear you could pop one of those on and if you need more absorbency you could put one of the abby gro boosters into it? Other than that can you get a couple of 3/4 length pants in a larger size just for at home?
