Need info on DSS involvement in the home?

First place as long as you are providing the care and needs for your daughter DSS will not doing anything. Too many people try to make an issue about using DSS as leverage to get back at someone or manipulates them which wastes resources terribly. What you need to do is seek counseling on how to deal with your mother in law or even invite a counselor or social worker over to your home while your mother in law is there to show her that you are not afraid of her threats. Your mother in law needs to be put into her place and told what the rules are period. You can either block or reject collect calls that come on your land-line phone just call the phone company. In order for someone to call from jail/prison they must have written approval from Security Personal so you can also contact them to let them know you do not want collect calls to your home phone. You might want to check her into a shelter or even renting her a room at the YWCA. It may cost you but at least she would be out of your hair. Especially if it is closer to where her bf is locked up. Another thing is getting her involved with a community program where she can go everyday. Just tell her "she has so much knowledge you think she should share it with others also", if you get my drift. She needs outside interests that can keep her busy and away from your family. Since she has bf in jail maybe she can find someone else that would be available everyday? I have listed a link that can give you some info on what CPS will look for or consider. Yes there should be protection against false allegations but when children are involved all must be check or verified these days. Hope this helps and good luck. Just remember there is a shortage of foster homes these days and they are promoting family unity more than ever.
