Do not stop following rules, giving rewards, and issuing discipline as necessary, because it helps show that routines are maintained. However, include fun time, together and alone.
Your goal is to aim at preventing your children from experiencing stress. Establishing structure and stability requires the collaboration of both parents.
The following can help in achieving these goals:
Show that you are calm and pleasant: for example, when interacting with your children even though you may be stressed inside.
A well-known textbook rule: make sure you talk about uncertain or stressful things away from your children’s presence.
Do not talk negatively about the situation or the future: refrain from talking negatively with your children. Practice staying positive and encouraging.
Look at positive aspects: emphasize all the good things in the situation and teach them to be grateful for what you all have e.g. like health, shelter, food etc.
Create an exercise where you ask your children to list what their positive aspects are about life and what they are grateful for each day.
These suggestions will set a good example for your kids and help them focus on the positive and feel that all is fine. It will automatically instill a sense of safety and stability.
