DP had an unexpected day off today. He has snapped at 4 year old DD and made her cry twice, huffed and puffed at 15 month old DS crying and constantly moaned at 8 year old DD since she came home, culminating in telling her to 'just shut up!' in the garden, leaving her running in in floods of tears. I spoke to him about it once I had put the DC to bed and he said she spoke in a rude tone which is why he snapped and said it. If one of the DC said 'shut up' to one of us or to each other they would be in trouble, I think it is extremely rude and ridiculous to have lost his temper with all the DC during what was supposed to be a bonus day off with them. Aibu?
