My son who is 6 years old spills a drink at least once every 2 weeks. I don't know how normal this is, but in my opinion, it's not that big a deal. I mean, of course cleanup is bothersome and the frequency of this is upsetting, but it's not something that I feel calls for disciplinary action. My husband however feels that at this point, it's happening because we have yet to really punish him. It's clearly evident that when he does it, he's completely sorry and sometimes will start crying because he feels bad. What would you do in this situation?
