Legal Issues With Child Custody?

Legal issues with child custody?
My husband and I used to be extremely violent and abused drugs. We have sought treatment but during our journey to become better people we had a few set backs and our parental rights to our twins have been terminated. We now, a year and a half later, have better lives, stable jobs and are off all drugs and alcohol and have had no police interventions at all. We are pregnant again and we need this baby. We (me) will literally go insane if we lose another child. We are sure the state of florida will rip the baby out our arms the minute I give birth so we want to leave state. What are the chances another states would do the same? I need all the help/tips anyone can give me, lawyers feel free to step in I need help. I already love this child more than I love myself, I would do anything to keep him. Im only 2 months so I have time to further prove my ability to safely and stabily care for a child.
