A stable life for Sierra & Savannah

Savannah is a vibrant, smart, happy 4 year old little girl. Her sister Sierra is 8 months old ( was born addicted & through multiple stds) & is right on her sisters heels with such an amazing personality. I have had the kids in my custody since April. In that time, their mother & father have not so much as asked if the children are still breathing. They are by the way, thriving! Savannah had experienced so much neglect in the hygiene department that we just recently had to have 8 root canals, 8 crowns, and 4 teeth pulled. Her parents are anything but role models. I have filed for custody. The 'dad' is in jail & the mother runs the streets. The paternal grandmother has filed a response to my motion & wants the children. Meanwhile, she lives with family (doesnt have her own home) & the neglect that Savannah experienced was at the hands of 'grandma' as well. Im not a begger... but any help would be amazing at helping to fight for a happy, healthy, stable life for these two little girls. They are where they need to be & we would appreciate any help in keeping it that way. Thank you.
