Thank you both for replying. I am going to contact CPS again and see what can be done. It may work out better this time since I am not planning to tell anyone else. I am pretty sure my mother tipped her off last time CPS got involved.
The kids are great kids and they deserve to have security in their lives. I know they are very loyal to their mother (she raised them to be) but she is not caring for them at all. She used to be a lot more attentive. It is sad to see what her addiction has done to her. Meth is not a joke.
