My son and his ex girlfriend are expecting a baby girl in February around the 21st or 22nd of the month in 2022. It was recently brought to our attention that when the baby is born, my son will have no rights to the baby. My son's ex girlfriend and her mother have already been holding the visitation over our heads when they get mad at us. How should we go about getting shared custody and visitation rights for both of them? How soon should we be trying to get this case in the court to be handled properly?
