Possible newborn

Wow, I guess I am on a possible placement role. There is another child that is on the way from a family that I am close with. I might as well be family. We spend a lot of time together. I have the kids from the family a lot. They said they are at their max with their placement and would not be able to take the newborn. They want me to take the baby once it comes into care. We have no clue how far along she is but the last baby is 9 months old already. She was pregnant with him when the 2 year old was only 6 months old. She also stopped coming to the visits right before severance and the last visit I saw her at she was looking pudgy in her stomach. I am praying that the baby will be protected as she was not clean and since the others are severed the only way that this will come into care right away is if she tests positive during pregnancy and the doctor reports it or the baby is born positive. CPS is not in her life now as she was severed in January. She was not happy and did not even come to the hearing she walked out of the mediation that she insisted on having and didn't even want to stay for. She made some poor choices and is very young. She could get her life together if she wanted but she does not have a good support system. I wish I could reach out to her but for the safety of her other three I cannot. I have them a lot. I also try to stay away from her side of town when I have the kids. I do not want to give her a chance to do anything crazy. Being in her state of mind she could do just about anything. I pray for her daily. I also pray for any unborn children.
