If at all possible, include the non-custodial/biological parent in the life of the children. Kids, especially teenagers, are greatly stabilized by seeing their parents unified. For this, mom and dad should try to minimize contention especially in front of the kids. Consistent parenting helps to alleviate childrens insecurity following divorce. Note: sometimes blended families occur because of the death of a parent. Of course, in that situation, this step does not apply. Online therapy can be helpful to get rid of such problems.
