He was removed from A&E to a ward because he no longer needed to be in A&E and the bed was required for other patients who may require it more - imagine the screaming abdabs if one of your relatives having a heart attack or stroke died because they couldn't get a bed because a child was waiting in it despite not needing to be there whilst a bed was being looked for.
The child went up to the ward and 4.30pm and was found a bed by 10:30pm. Granted it's not ideal but he was found a bed by night time so it's not as if the child was prevented from a normal sleeping pattern, albeit 10:30pm being slightly later. It is not unreasonable for a family to be shown to the waiting area - nurses and medical staff were still available should they have been required.
It's because of the ridiculous suing culture which has developed which meant this child was not able to use a camp bed. He was six years old and, as several of you have pointed out, ill. Ill children are restless children - if the parents had not been paying attention and the child rolled out of bed and hurt himself, there'd be even more hell to pay.
It's a bad issue - but until more money is and resources are put into the NHS this will not improve. Too many people are too dependent on A&E for wholly inappropriate things - including coughs, colds, headaches, toothaches and general malaise - and this affects the entire process. Likewise, there's a lot of "bed blocking" - patients who need occy health or community support and can't get it so are left in hospital waiting til it can be sorted.
