Never a JW but when I decided to have children the three things that would never be repeated.
I vowed not to drink once I had children except on rare occasions so when my daughter became a young adult she thought social drinking was a glass of wine once every six months.
When my children broke the rules we sat down and talked about what they did and why they did it. There was no hitting or spanking when they got to a certain age I could just look across the room with the motherly look and they knew oops maybe I should not be doing this.
Most importantly I taught my children how to make decisions at a very early age. Giving them choices with simple things first. All along the way giving them the resources to research, think and choose what they wanted. As young adults they will still come to me and ask me what I think they should do on some things but I will still tell them this is my opinion BUT I expect you to go do your research and make your own decision for what will best fit your long range needs. You will never hurt my feelings if you choose a plan that differs from my opinion.
