I am a dad and I am single. My ex and I share child care on an equal basis. I looked up 'single parent' on Wikipedia and it equates 'single parent with 'lone parent'. So I'm not one of those. I asked my ex if she considered herself to be a single mum and she said no because she only looks after the DCs part time unlike a single parent. When I call myself plain old 'dad' there's a tendancy to assume I live with a partner/DCs mum. I'm not actively looking for a lable but I was just pondering this.
