I fee like a bad mum. I'm a stay at home mum to twins and the other day I couldn't take it anymore. I changed my son's nappy roughly. I didn't hurt him but I didn't try to make him stop crying and I was just like , "sit there!" And told them to stop winging! They were winging and I just shouted - "what?!" The look they gave me was like a sad face and I feel so guilty about it.
