"Parental responsibilities" means the power to make decisions for a child and to spend time with them. This used to be called "custody," but this term is no longer used in Illinois.
A court order for parental responsibilities will explain what decision-making power each parent has and how much parenting time they get.
You do not need a court order if you are the natural mother, or if you get along with the other parent. But without an order, it may be hard to get the courts or police to help you if you have a problem with the other parent.
A court order will protect each parent's rights. It will also allow you to make the other parent follow the rules about parental responsibilities.
