I think the biggest challenge in raising teens is keeping your relationship doors open. As much as you try as a parent, teenagers are not going to agree with what you want. I have learned to back off some,and give them some room. Yes I have made my share of mistakes, and I have some regrets, even bad decisions....but, my relationship with my children is wonderful. I am grateful for both of my children. I try to encourage them as they go along their own way.
I am there for them and I try and listen. Being a family is not always easy but the rewards later in their adult years is worth it.
