Every parent in Illinois wants to raise well-balanced and emotionally stable children. For this to happen, it's often important that the kids have a relationship with both of their parents. If the parents are separated, however, relationships could suffer. That's why exes should take steps to co-parent effectively.
While there are likely serious issues that caused the parents to split up, they will need to come together and do what is best for their children. They should openly communicate about the parenting schedule. When the children see that each ex-spouse is working together for their well-being, they are likely to feel a sense of security.
