As a parent, I have observed that kids observe YOU. Plain and simple. You want them to do something? You do it first and show them. For example, eating together as a family on Dining Table. My wife and I would just eat on the sofa and kids started expecting the same. They would run around during dinner time. One day, we decided to stick to a plan that we will eat only on the table. It took a bit of a time but kids are now eating on the table 90% of the time (not quite there with 100% yet but that is how it is with kids. No absolutes :))
So before you think about setting up systems for THEM, setup systems for YOU which they will just follow. Really hard as adults to change our own habits but it does wonders.
All the best. Raising kids is the hardest thing I have ever done and I have done a lot of hard things in my life. You will need a bit of luck, tons of support from family and most importantly: a clear head :)
