Parenting is a lifelong job. Remember, you don't divorce your children. Children going through separation and divorce need a lot of stability to anchor them during the stressful times of the early stages. Change as little as possible, especially at first. Do not alter the way you discipline and reward your child.
Children feel safest when things are familiar.
Another important point is that tough times are the best times to be more affectionate. A few extra hugs are just what the doctor ordered for times like these. Be careful, of course, not to overdo this, but a little more affection can make a big difference to children who are feeling scared or lonely. It is, nevertheless, equally important to avoid letting your children take care of you, no matter how much you need the hugs too. Many children try to act like adults and want to help and comfort their parents, who they can see are in more distress than usual.
