First things first you need to have DH on the same page or its not going to work. I really believe in parenting unitedly. Its the most successful way because its consistant. If there's two sets of rules and either parent undermining or overbearing another its not going to work. Maybe you can come to some comprimise with your DH and say ok we'll try it my way for a week and see how it goes. I bet if you can both work together you'll notice a difference. Also I think this has very much to do with the fact you are 40 wks pregnant and you are not yourself and they are clever little cookies and would pick up on that. Also change is huge for kids so that would definitely be playing a part too. Maybe try alternate ways to combat bad behaviour I'm not sure what you do now? But paris will often have quiet time in her room if she's being silly or not listening. Then we'll talk it through etc. Another thing is to make sure that if there is a type of behaviour that isn't ok after the situation has cooled or calmed follow it through, talk it out so its understood and perhaps have them (as their age permits) talk back to you about the situation and whats ok behaviour and whats not. This can be all very time consuming but it does work and it is worth it. The other thing too is to praise them for doing the good behaviour especially when they aren't expecting it, so if you see them playing nicely or when Evan does listen (even if its something minute) tell him you're really happy that he did x and you are proud of him etc. So that it feels good to do the good stuff. Its kinda like an emotional reward. And if he's a physical kid walk past and give him a tickle or a cuddle or whatever it is that he might like if he's not into words.

Thats all I can suggest for now I'll come back and add more later and feel free to tell me tried that done that NEXT lol!
