Feck locking her in jail, the woman hasnt even given that child a choice of lifestyle, I mean sure he/she wouldnt have the best lifestyle but there was choices they could have made.
This type of person, your right, should not have rights to their children at all and should be on permanent tag in their houses. As Sam has made clear though, A lot of courts favour the mother in most cases, which is sad IMO, because the mother is not always the best option as you can clearly see.
LOCK HER UP and let the children live their lives (hopefully free of drugs)
