Can CYFD take children during cancer treatment and prevent transplant?

Hello. My husband has AML. He is 56 & we just had a baby. She is now 20 months & 2 boys 12 & 19. Our two younger children were taken from the hospital NICU. While my husband was in chemotherapy treatment. They charged us with medical neglect & educational neglect. My son who is extremely smart & was reading at an 11 th grade level is by far from being stupid. My daughter was forced to have a feeding tube placed when she never needed it. It stayed in her gut for 10 months and never used it but for the first days to get her home to my brother. My husband was served papers in the hospital. When he was released he needed a bone marrow transplant, but was told he needed to get the CYFD CASE closed first. He was so healthy & now he's sick again. Still CYFD has not given our kids back and my husband is dieing. This is so unfair to all of us cuz they deserve every moment they could have with their Dad. I wish there was Justice for this whole situation. Anyone with help
