Suggest Treatment For Pneumonia

hi wondering my my twin son hes 8 months old and has been sick sense hes been 3,4 weeks old coughing up blood, they then noticed while trying to find out where blood was coming from did tests of urine and his calcium was very high should only been 0.7 hes was 7. treated him for that and then did mri see what was going on notced three spots on the brain. did many tests trying to understand what was wrong with Gage. He developed pneumonia twicw in hospital over that time. so booked follow up on mri to see if spots where gone the then noticed a subdural hematomas on brain and subdural hemorrhage behind eyes they then did a steakal survey on his body and then seen two possible three hair line fractures. sense then he developed two more pneumonias and bronchiolitis twice. we know our baby boy is sick but no one will help! also twin sister had a small subdural hematomas. hope to hear some answers be greatly appreciated.
