K.B.
G'Morning K., he's a little stinker for sure. So if he laughs make him wear his yucky underwear for a little while. Then make him change his cloths and clean himself up. I know easier said then done. Sounds harsh too, sometimes ya gotta do the hard time to get the results you want. When his little hinny starts hurting or itching from having dried poop stuck on his rear, he just might not think its so funny anymore. Worth a try any way if you can stand the aroma wafting out of his britches. ;)
One of our gr sons was doing this to a extent, he would hold it in so long, when he finally went he couldn't make it to the bathroom quick enough. Reason for holding it in was it would hurt.. WELL my words I guess it would. How a small child passes something That LARGE is beyond words.
Anyway K. give it a shot, maybe some other Awesome Mama's have a solution for you that isn't as smelly. :)
God Bless your family
Thank you K.'s hubby for serving and protecting us all
