Re: step children
Firstly I'd like to say , you must be a very strong woman to take on all of this.
One idea might be to sit everyone down together and discuss the assues, but it is important the your fiance stands behind you fully in everything you suggest, otherwise they might rebel against you even more.
To get him to realise the disipline issues, you might start reading bookson the issue and involve him in what you read, ideas supposedly coming from outside source might be easier for him to work with.
How about this idea as an off the wall idea.
Put a complaints box on top of TV and, and say arguements will not be entertained put complaint in box , and every friday evening you wil all sit around table and open the box. Again it is important that he is on your side all the way.
Best of luck I hope you are able to sort things out
