S.S.
right now no matter what ur son needs u call the grandmother n see if u can bring ur son over for a visit since he can't get to now his father physically its not to late for him to have a relationship with his family they can tell him about his father maybe give him something that belonged to him so he can feel close like the other moms have said counseling is also a good idea try that along with what i suggested hopefully it helps. good luck.
