GAL Duties?

I know a couple who were arrested for shaken baby syndrome, and the baby is still in the hospital. The other children in the home were placed in foster care, and a single guardian ad litem was assigned for all of the children. A lot of what I've been told about the GAL doesn't feel appropriate. I'm wondering if anyone has any insight into if the things she has told the family are consistent with how a guardian ad litem should be handling this situation.

First, she is a paralegal who volunteered for this case after learning about it, apparently. I know they can be volunteers, but is it true they can volunteer for a particular case, or are they assigned by the court?

The GAL went to the hospital (without an appointment) that the baby is in to speak to one of the doctors treating the baby. This one doctor told her he believes this was not child abuse. Other treating doctors believe it is child abuse. She went back to the family (apparently showed up at their house) and told them she does not believe the couple should have been arrested as this doctor said it's not abuse, the charges should/will be dropped, and that they are going to have a huge lawsuit against the police department. Apparently, she now wants to request the body cam footage from the cops' bodycam from the day 911 was called and the baby was taken to the ER to show the cops had a bias against the couple.

Also, the day the baby was admitted to the hospital, the hospital banned everyone -- the parents and all family -- from getting information on the baby or anyone visiting. Nobody had been arrested yet so I'm not clear exactly how that happened, but as far as I'm told that ban is still in place. Is it appropriate for the GAL to be going to the family, giving them the information the hospital has given her on the baby now, when the hospital has banned anyone from getting information? She has told them the baby will be released, the information on the doctor believing this was not abuse, and that the baby is having new brain bleeds, etc.

Lastly, the other children that were placed in foster care does not have the same father as the baby. The GAL told the mother's family that if the mother (who is in jail) would sign temporary custody papers giving the family custody, the other children will be released from foster care and given to the family. This feels inappropriate and out of the scope of her duties to be offering this type of legal advice. She has offered to take the custody papers to the jail to have the mother sign.

Is this all normal for a GAL to become so involved and so partial towards a family and advising them of things like a couple should not have been arrested/will be released, requesting body cam video, giving out information to the family that the hospital does not want released, advising them they will have a lawsuit against the police department, and advising the mother to sign over custody?
