The King of Wands indicates that you need to give your children guidance based on discipline and logic. You need to be a solid and responsible parent so that your children can learn the lessons they need to embark on their growth journey. The mind is important because you need to be able to make logical and thoughtful decisions in any situation.
The Empress on the obverse indicates that you should take care of your children's bodies. You should ensure that they get good nutrition, regular healthy physical activity, and adequate sleep. You should also encourage them to take care of their mental health by avoiding stressful or demanding situations.
The Hanged Man suggests that you need to support your children in recognizing positive emotions and feelings within themselves. You have to show them how to handle negative emotions, how to listen to their own thoughts, and how to approach life's problems with the right understanding. Also, you need to be a safe point of reference for them to retreat to when they need advice or comfort.
The answer to the question is that to be a good parent your children need you as a guide of the mind, both as a support of the body, and as a support of the soul. You must encourage them to be responsible, to take care of their physical and mental well-being, and to learn to manage their emotions. You must also remember that they should know that they can always count on you when they need it.
