Greetings. Generally, there is no penalty if one of the parents does not show up for visitation. One of the things your spouse can do is file a motion to modify custody, asking the court to curtail the time the father has with the children and/or for babysitting costs if the other parent has plans on the time of the other party. Best of luck.
