How would a person change the result of a court hearing involving children. My daughter went to court the lawyers

Long story short my daughter has 3 children when she had her last one she suffered from post partem depressions she was reported to social services she then moved out of my residence to move in with her then fiance. 2 months in the social service removed the children she had no support from her partner any blamed her for everything. We have gone to meetings involving his parents myself and social services every 3 months there seemed to be a change in supervisors putting us back to the beginning .my daughter has gone to a doctor and to counseling she has been on her medication since she has grown as a person . She has also done all the courses she has found gone to parent link social services has not given her any credit for all she has done the last case worker we had asked that question as well ,her doctor has asked the same question. I have asked this as well there does not seem to be an answer instead we go from a visit with childern every week to 1 a month and being told the other grandparents are going to adopt. To start with there was an issue with her youngest child gaing weight where we found that he could not tolerate milk. Social services demanded that she put him back on formula which did not help so they said she was neglecting her children,what I still do not understand is why batter her down when she is down already I also feel that the person just wanted to prove a point I am concerned for my grandchildren at this point.

Hi I am happy with our conversation and will put your advice to use. This has helped a lot and gives me a some hope in the days ahead . Thank you very much
