One thing that I learned as I parented my children is that cultivating a close relationship with them ALWAYS pays off. At times they misbehave, and a lot of the misbehavior is age/stage related, but when you have the relationship, you have the necessary basis for them to WANT to obey you. If you have that, you have SO much. If you don't have a solid relationship....invest in it. Invest, invest, invest.
I never expected my children to obey like automatons. I know they are people, just as I am. They may have internal struggles as they get to the point of obeying (just like I do.) As their parent at times I enforce the rules, and at other times I serve as a resource to HELP them. Actually at this point I only have one child at home, so I should stop writing "them, them" so much! But actually, I still HELP the older children, by being available to talk and listen and by praying for them.
I am so excited for you. Welcome!
