Most people find other people's children irritating but I find my own incredibly annoying. They whinge, moan, fight, demand, ask me questions constantly, invade my privacy constantly, vie for my attention constantly, talk at me at the same time... I feel like my head is going to explode. Is this normal or is it because I am a struggling single full time working mum? They seem to be completely spoilt although they actually get next to nothing and spend most of their days including holidays in childcare or school. I don't understand!
