My husband does a lot with our children and they have a good relationship. However he can be quite irritable and bad tempered. Tonight he was helping them get ready for bed. They started crying for me and told me that Daddy had told them to 'shut their mouths'. I feel like this is a really unpleasant thing to say to 2 small kids. I can't imagine ever talking to them in this way and I am anxious that he thinks it is ok. Am I overreacting?
