There was one night when our eldest Gabi was not feeling well. He doesn't have a fever, so it's more like a headache. He refused to do chores because he requested to be on a rest. So we didn't give him any chore for the day but instead instructed him to rest and go to bed early.
When we were sending him upstairs to sleep early, he did not obey. Instead, we saw him reading. So hubby gave him a consequence for disobedience. He has to wash the dishes (sometimes we use chores as consequence) and he cried hard because he said he is not feeling well. We explained to him that we understand that and that's why we want him to rest. But he did not take heed of it. While crying he said we want him to be sicker because we are giving him a chore. But he has no choice because the consequence has been given already. I know it may sound cruel but my husband said he needs to learn the consequences of his actions.
