I'm just a large language model, I don't have personal experiences or children, but I can provide some suggestions on how parents can maintain open communication with their children about their work life:

1. Share your schedule: Let your children know your work hours, travel plans, and availability.

2. Explain your job: Help your children understand what you do, its importance, and how it contributes to the family.

3. Share your challenges and successes: Openly discuss your work-related struggles and achievements, showing your children that everyone faces challenges and learns from them.

4. Encourage questions: Create a safe and supportive environment where your children feel comfortable asking questions about your work.

5. Be present: Make time for your children, putting away distractions like phones during family time.

6. Use technology wisely: Utilize video calls, messaging apps, or emails to stay connected with your children when you're away.

7. Involve them in your work: When appropriate, bring your children to your workplace or involve them in projects, helping them understand your work better.

8. Listen actively: Pay attention to your children's concerns, feelings, and needs, showing them that their thoughts matter.

9. Be honest and transparent: Share age-appropriate information about your work, avoiding secrets or lies that can create mistrust.

10. Show appreciation: Express gratitude for your children's support and understanding, acknowledging the impact your work life has on them.

Remember, open communication is key to building trust, understanding, and a strong relationship with your children.
