  you are partially correct. You need to detox the baby after birth.

  Not in all cases, it will depend on other factors like the health/weight of the baby. Sometimes the care might be supportive, sometimes medication is needed to control the more severe withdrawal symptoms; in this case they are not given the same drug used by their mother, but a similiar drug from the same family, with the dosage being reduced gradually.
