I am currently in Idaho. Two months before the birth, mother moved to NM with her boyfriend. She was using off and on during the entire pregnancy, laughing about it, and was even fired from her job for showing up intoxicated while pregnant. My son was born with cocaine in his system and was placed in new mexico foster care. He is with the mother at a rehab for mothers with newborns, but is still technically in NM state care. I have had some conversations with his case manager, but they won't do much for me until paternity is established, and it seems they have been very much won over by the mother and believe whatever poison she is spewing about me. They have been telling me since the birth they will establish paternity but at this point are clearly dragging their feet. I have had very limited communication with the mother since a couple weeks after we found out she was pregnant, although i have definitely tried to maintain a cordial relationship. She is very bitter about the breakup and her current boyfriend has total access to all her communications via icloud as part of the terms for his unlimited financial support. I just want to be in my son's life. What steps can I take now and for the inevitable custody battle down the road? At this point she is clean and sober as she is in the rehab but her boyfriend has no plans to quit and as soon as she is allowed to move back there she will resume using. The boyfriend was deemed as unsafe by CYFD due to his refusal to take a drug test after she tried to claim he was the father. Thank you
