It's easy to forget that the children are also experiencing a great sense of loss. They just express it differently. For most children, adjustment comes in spurts, with most kids returning to some kind of normal behavior in about six months, depending on the amount of conflict in the divorce. Even if you have to put on an act, do it for the kids. Educate yourself about grief.
Parents can unknowingly pass on their anxieties and fears to their children.
This will allow the kids to express their grief, which will allow them to let go of it. Wrap your child in relationship. Spend time with the kids, ask them how they're doing and really listen to their answers. If a child wants to be alone, allow him or her that space. Create transition rituals.
