Help Keianna with her kidney

We recently found out that Keianna had a blockage in her kidney. It is causing her massive pain. She is 6 years old and had gone through test that you wouldn't want done on yourself. She is a funny, curious, exciting, girl. She our Buggiez!! Friendly to everyone. Loves to ask questions.
Currently my husband and I work full time working opposite shifts to care for our family of 8. I would be taking time off of work, exhausting my sick pay and vacation time which is currently at 36 hours. Then hopefully I'm eligible for OFMLA which protects my job without pay. My husband would use his sick pay to help make trips and care for our other kids in an emergency. I wouldn't ask for help because I'm stubborn. But I'm too the point where I need to. Please help me help Keianna and our family.
