Child Protection

My two grandchildren are being harmed by their mother, her new boyfriend and the grandfather who they live with. They are 2 & 3yrs old. There have been repeated child welfare reports over the past 3yrs. In January the 3yr old was assaulted, in February the 2yr old was assaulted as well as their father and 2 others in front of the 3yr old. Despite police reports etc child services won't remove them. They keep giving their mother 'another chance'. There is a lot of mental illness and substance abuse involved. The grandfather has also had allegations of sexual assault against minors. Please pray Father removes them rapidly. They have lived with me in the past and I am seeking to care for them permanently.
