I've had to take DD to A&E three times recently, experiencing 2 different hospitals.
Hospital 1 in the North of England: triaged within half an hour of arriving, in a cubicle with thorough examination by Nurse Practitioner after an hour and saw a Dr within 2 hours. Bloods and scan done within 3 hours of arriving. 8 hours between arriving and getting a bed on a ward but we were well looked after during those hours.
Hospital 2, a well respected hospital in the South of England: arrived with letter from GP stating the serious medical history and the need for a blood test and scan. Triaged after about an hour then left to wait for 5 hours before we saw a Dr who arranged for her to be admitted. A&E never got around to doing the blood test. It was done on the ward which we go onto at 3am, 9 hours after arriving at the hospital. I had to be very forceful to get the scan she needed which picked up on a problem that required surgery.
I'm sure children are dying unnecessarily, especially those whose parents will struggle to advocate for them for whatever reason. At both hospitals I had to fight for the care my daughter needed because 'she looks well' but I knew there was something seriously wrong.
That being said, we have been looked after by some truly fantastic nurses and doctors along the way and it is not the staff's fault that things are in this state.
In both A&E settings there were lots of parents there just to get ABs for their kids' chest infections which must be due to poor access to GP care.
I also think A&E need a separate area for people who go in with vomiting bugs. Even if you don't give a shit about everyone else in A&E catching these bugs it doesn't make any sense from an operational stance to have patients who may well be admitted to hospital wards sitting next to people who are vomiting to then bring these bugs onto the wards.
