This is something i swore i would never do (pre-parent)
But is not something ive achieved. Dont get me wrong it isnt a regular thing but does happen occasionally
and when it does its usually a arguement on the worse end of the spectrum and its going round in my head at the time to gain control and stop but i dont always succeed.
Then i feel such an awful mummy afterwards 
Someone else as said to me its unhealthly for children to never hear arguing/shouting as it is part of life and if they never experience they wont be able to cope with it whne they need to...not sure i agree although i can see the logic sort of
