1. When your child confides in you, let him feel that he did the right thing. Even if he is at mistake, control the urge to take the issue to another adult who might intentionally or accidentally spill it out in front of the child. Taking to someone you really trust or a therapist might be the best if you think that you need help on something related to your child.
2. Don't tower over your child. Sit down at their level and talk with compassion. Try to keep your work/family worries at bay when you communicate with your child.
3. Active listening is important when you talk to your child. And it requires energy on your part, so if you you are already tired, either take rest and spend time with your child later or make them understand that you had a long day and you will participate in a better way afterwards.
4. Don't share things with your child, if they are not emotionally mature enough to handle them. For example, issue of the family or work related issues. Observe and reflect the impact that they would put on the child. But don't withhold matters that make them learn about problem solving and other good things about work/any other matter.
5. When a child explains about something to you, or asking for your advice. Listen to the whole thing and then offer help. Don't lose patience and just jump to give the general rules and regulations that they should follow.
6. Spend time with them outdoors, ditch your phone and teach them the importance of exercise and non-screen time.
7. Don't use derogatory words for your children and don't make them feel that they know very little about the world because they are a child. We learn throughout our lives. And lastly accept them for the person they are. And let them know that.
