Is there any legal recourse for a NCP who refuses to visit his infant son for 1 full month?

Why are you alienating the person who is going to be taking care of your son while he is at his fathers house? She also needs to bond with the child. You say his father only feeds, rocks and changes the child...the baby is only 4 months what do you expect him to do play ball with him. You need to find a way to get along as you will be dealing with this for the next 18 years.
