I think it's about the first response when they have transgressed, as well as how you start and end the day. I think it's about saying in a calm way that you love them, regardless of their acheivements, and regardless of their mistakes;It's about a verbal reassuance and in how you respond when they "mess up!"
Interesting advice on how to balance unconditional love and teaching obedience.
When our kids test our patience, it can difficult to love unconditionally. I recommend just reminding yourself why you decided to be a parent. There are always reasons to love your kids no matter what :)
I recently told my teenager who is kind of rebelling and pushing back with my rules that I will love him no matter what. But I may not always like his decisions or actions. I told him I will love him no matter the career he chooses or if he attends college or not. That my job as his mom is to help guide him to be a polite, productive and happy adult who contributes to society but I will love him regardless of the paths he chooses!
