Sarah's mom needs help w Chemo cost

My sweet precious niece Sarah 7-1/2 years old has been diagnosed with Ewing's Sarcoma (a rare children's bone cancer)  Although Sarah and her little sister are  amazing little girls, single mom is facing the struggle of not being able to work while being by Sarahs side 3-5 days a week every 2 weeks for 12 months while Sarah has her Chemo Treatments. Sarahs mother has health insurance but with little work income coming in and a a 30% deductible funds are going to be very difficult. Any donation would be greatly appreciated to help these 3 sweet ladies.
