Creating a safe space where our children can talk about anything takes work but is incredibly important in building and strengthening our relationships.
Our kids will have questions about complex topics, and if they don't feel they can come to us, they will seek out answers elsewhere and may get information that is incorrect or goes against our belief system.
Children ask difficult questions because they are trying to make sense of the world and their place in it. We want our kids to feel comfortable asking difficult questions and need to permit them to do so. 
We understand that sometimes these complex topics are triggering and can cause parents to have an emotional response or to shut down. As parents, we want to create gates, not walls, when our children approach us. Gates allow us to guide and understand where walls teach our children that what they are curious about is a problem.
The skill of Effective Communication helps parents create those gates by helping both parties feel listened to and understood. Effective Communication works with children of all ages and can be used when discussing any topics. When parents use Effective Communication, they permit their children to talk about important things to them, which, in turn,  fortifies their relationship.
