The evidence is quite strong that if you can keep yourself in remission, which may require continual available treatment, your children are less affected; again, this is the case when we look at populations as a whole. On an individual level you might explain that you understand that he/she sees you looking sad but you are taking care of this problem. You might say, “it’s a grownup problem called depression and Mommy is getting help for it.” If you are still concerned, consider having a consultation with a clinical expert who specializes in working with children. A therapist can talk with you about the things that worry you and suggest ways you can engage your child in a discussion.
