This was June last year so during lockdown. Dh was wfh.
A) How long were they unwell before you took them to hospital?
He had tummy ache that morning(7am), and didn't want to get up, but other than that was fine. I got home from work and he was still in bed, which was very unusual for him. He'd got a slight temperature, which was usual for him with any illness. Even more unusual he hadn't eaten anything. The only one of us who had been near people was me, and no one I'd been near had had any tummy bugs so I was immediately thinking of appendicitis.
I got home at 6pm, phoned the GP who said basically all they'd do was send me to A&E to check for appendicitis; it was unlikely they could rule it out. Told me to take an overnight bag. So I went straight down, was down there about 6:30pm/7pm. He started vomiting when he moved.
B) How long were they in A&E before being admitted?
never got into A&E. Because he had a covid symptom (temperature) we were sent straight up to the ward. The surgeons wanted to send him home because he said the pain was about 2/10 (he's got a very strong pain threshold, he never got above 4!), but the paediatricians said no, they were pretty certain it was appendicitis and put him straight on a drip. We were in a private ward (waiting covid test result) before 9pm, and told to expect him to be called first thing from 7am.
C) How quickly did they operate?
Now this is where it went a bit slow. We'd been told to be ready at 7am. However they got a number of emergencies in and he actually went down at 7pm. According to the hospital notes he'd deteriorated in that time. He was lying in bed watching the A-team.
I felt I was the one who deteriorated, as I wasn't allowed off the ward until the covid test came back and I was starving. I eventually persuaded one of the nurses to bring me something which was cold fish fingers. :D
He also was very pleased that he'd crossed something off his bucket list-having a drip in. He is a funny child! So he had a lot of conversations about the drip.
I was actually quite glad that he had been bumped when it came down to it. He arrived to a new surgical team, which was a good thing because the normal operation takes around an hour. His appendix was in the wrong place and twisted around. I was eventually told he was in recovery 4.5 hours later. So if they'd thought they could just squeeze him in at the end of a shift it could have been some very tired people by the end.
He was the only person in recovery, so they let me come. His only recollection of there was the nurse had a bottle of cola and didn't let him have some!! 
D) Had it perforated or not?
No, and they didn't think it was imminent either, it was swollen, but not badly.
If it had been during normal times I'd have assumed he had a tummy bug, as that's how he was presenting, and it would have been at least 24 hours longer I suspect before I'd have started to think there was more to it. They said we'd caught it nice and early.
Recovery was a bit rough though. He always reacts badly to anaesthetics, and takes ages to come round.
This time he woke at 6am the next morning, starving. So he ate 4 bowls of cereal. I woke at 7am, and he was beginning to flag. By 9am he was back to dozing totally, and his O2 went down etc. Couldn't get him to eat anything at all after that, and all he wanted to do was sleep.
The nurses were lovely and asked what he really wanted to eat as a treat and he said a cheese toasty and cola to drink. They got it for him, and he had about 2 bites of the sandwich and a mouthful of drink.
Having expected him to go home that day when I woke, they wouldn't even consider it until halfway through the next day when he managed a little to eat (yoghurt) and we got him up and moving (although he vomited when he first stood up).
And on the way out he got to cross another thing off his bucket list: he was taken down to the car in a wheelchair.
I haven't dared ask what else in on this bucket list. 🤣🤣🤣
