I know IABU but is it normal to be so irritated by one of your dc (my 5 yr old dd but not my 10 yr old.) It's the constant nagging, saying 'mum' in a whingey voice all day long, the talking, the questions, the not leaving my side. Even her loud deep voice and coughing and sneezing grate on me (I am being mean now I know.) She is generally just being 5. I am trying to be patient; this morning she said 'why are you saying that's nice when it's not?' Is it me or am I just not cut out for motherhood?
