I don't know what you have done to get your child back and am not judging you. You need to call the police! That family offering to adopt when they have you is parental alienation, not only that, if they have taken custody of your child without permission, that is kidnapping! If you do not report it, it is abandonment on your part. It seems that your kid has control of the situation and you need to take charge as a parent. There is plenty of free help available to you. Do not be a victim and take control. May God bless you with strength and good health so that you may save your child. May the Lord send people your way to help in this situation. I ask this in Jesus name, Amen.
