Does he behave the same way for wet diapers? If not, it could be he might have hurt himself when he pooped and clean cause pain to him. This happened to my kids and after identifying the issue I started to ensure they have lot of vegetables/fruits and water. On top of it, I helped them to do baby/tcm massage to improve the movement of bowel. After awhile, they don’t cry and throw temper during the diaper change anymore.
