Having been in hospital for 10 days aged 3yo, I thought I'd share my experience.
My first memory in the hospital was refusing to take the medicine. So they injected it in me. I thought that was definitely cheating. I don't recall feeling it was traumatic, but simply that they had cheated me.
I'll add that I didn't refuse again though.
But I remember the nurse giving me medicine one morning, and promptly vomiting it straight back up. I remember looking at her thinking "well, you did make me take it. Serve you right." 🤣
Visiting times were in the afternoon. I don't remember particularly wishing mum was there at any point particularly in the morning. I think because no parents were there, it didn't worry me, and I don't remember any children crying for parents. There was a huge playroom, but I only really remember that in the morning they decided to hoover the ward, and put us all in the cots while they did it. I didn't like the noise, and couldn't wait to get into the playroom. I asked one of the nurses if I could go through to it while they were hoovering, and she said we had to stay in the cots. But then she came back and told me that I could come and do a "job" with her, so we went into the playroom and put the toys away. I felt really proud that I was helping.
However I remember one night deciding I was going to make sure mum was the last parent to go, and see how long I could keep her there. So every time she got up to go, I started screaming. As the night nurse ushered her out and the door closed (probably on her having a cry) I remember thinking "thank goodness, I really want to go to sleep".
I woke during the night once and the night nurse was there with her head down on the desk sleeping. I remember finding it quite comforting that she was there.
I struck up a friendship with the boy next to me early one morning. He was having his tonsils out. We had a giggle together as one of the toddlers managed to reach the jug of water on her bedside cabinet and tip it over the nurse. I shared my biscuit with him, because he was hungry, which was a pity as he had a sign on his cot saying "nil by mouth", which meant precisely zilch to either of us. He was delighted to have another day before he went into surgery, and the nurses sat us both down and tried to explain it. We didn't understand, and I passed him another biscuit, feeling delightfully naughty, until the nurse told us that he could eat now because he couldn't have the surgery until tomorrow now, and fetched us a bowl of ice cream to share (I think we even shared a spoon - whoopee for infection control) which we were both delighted with and thought this was well worth it. We planned on doing the same the next day, but the nurses obviously foiled us by taking him out for surgery before I was awake. We were not pleased and he didn't even fancy ice cream when he came round, so I helpfully ate what I wanted and tried to feed him the rest.
The only food I liked of the main courses was something I described as tomato soup with bits in. I discovered many years later this was minestrone soup, but mum never made the connection.
I remember mum coming with a bunch of seedless grapes just for me. We didn't often have grapes and even less often seedless ones because of the cost, and I didn't want to eat them at first because they looked so lovely and were all mine. I wouldn't let the nurse throw the stalk away when I'd finished.
There were two identical twins that arrived towards the end of my stay. I'd guess they were about 6-7yo, because they seemed huge to me. They rushed round shouting and broke things and I was scared. They moved one of them to another ward (I remember their mum being really upset when she came, because she could only be with one at once) and the other they put a top on the cot so he couldn't get out. He was angry. Looking back it was cruel, but at the time, I was really relieved because they'd scared me. That was probably the thing I found most scary at the time.
We had baths in a room full of baths. They were really cold, and I remember mum trying to sneak a little bit more hot in for me. It was still cold.
The only thing that I think effected me, was every night I went to sleep with a blanket over me (still got the tartan woollen blanket). Every morning I woke with it folded neatly in my cupboard. I still hate sleeping without anything over me.
So that was my 10 day stay. I don't remember it all, and I remember a few things about the treatment like being tipped facing down for "tip and tap" which they tried to make it sound like a game, but I thought it was a bit silly. And going to have an x-ray and them showing me the x-ray. I was disappointed because I was expecting it to be a colour photo of my lungs and, of course, it wasn't.
There are bits I don't remember. Apparently I reacted badly to one of the early medication they gave me. Only thing I remember about that was they changed the first really nasty tasting medicine to one that didn't taste too bad, so I was happy about that.
