about 3yrs ago i got a call from my dad stating that my sister’s husband was making meth in their apartment, he husband was very abusive to her and myself i lived with her and him for a few month and while there he would beat my sister i would have to rip him off of her and take matters into my own hands well when i moved out i guess a few months later he started making meth in their apartment he used to buy it, do it and sell some their apartment got raided and my sister got charged with 3 counts of child endangerment and was put in jail her kids were taken away and placed with his parents. They are unfit parents, their sons are both meth addicts and they support their habits bail them out of jail, etc… my sister has done everything the courts have asked her to do to get her kids back and everytime they go to court they claim she hasnt done something she was supposed to. I want to step in and get guardianship of them but not really sure how i would go about doing it. i am planning on getting a house big enough for them i have two boys of my own. those girls are not getting taken care of the way they should be. my sisters mother and father in law put chloe who was 3 or 4 at the time on medication because she wouldnt sit still and said she had ADD i dont know who in their right mind would put a TODDLER on medication like that she went from being bubbly and happy 24/7 to a walking zombie. i want those kids out of their so bad, i just want to see them happy again the way they used to be. They live in Iowa so how would i go about that in iowa courts.
