JT,
My suggestion would be to go to court and have someone get legal guardianship for your grandson. Your son is in no position right now to contest it because of his life situation.
This would give you and/or his other grandma the power to protect him. You could even try to set up monitored visitation for your son.
If something happens before you are able to do this, then you can call Child Protective Services.
That's what it is called in California. I'm not sure of the name in your state.
I was fortunate with my son because his mother was willing to have my help. I hid her and sent her a plane ticket out of state to be by her mother. Your situation is different.
Hugs,
MG
P.S. Oh my God, I just noticed your avatar picture. I am rolling on the floor
