Ok I can see that not everyone here has kids otherwise they would realise that giving a one year old 'time out' really is not going to work, however a tap on the hand with a nice clear NO is very effective.

Perhaps I am meant to reason with them ? lol.

And as for shouting at children I think its so wrong ! losing your temper with them is not the right way to go about things, it should be done in a nice calm way.
