A father is fighting a hospital's attempt to withdraw support keeping his baby son alive. The one-year-old, known as Baby RB for legal reasons, was born with a rare, genetic muscle condition that makes it hard for him to breathe independently. His parents are going to the High Court - the mother is reportedly supporting the hospital's bid. The father's lawyers argue that the boy's brain is unaffected, meaning he can see, hear, interact and play. Despite having to remain in hospital and being dependent on a ventilator to breathe, he enjoys having stories read to him and listening to music, they say. The lawyers are submitting video footage to the court, which they say shows him playing with his toys. But the hospital says that Baby RB's quality of life is so low that it would not be in his best interests to try to save him. Baby RB was born with congenital myasthenic syndrome and has been in hospital since birth.
