My kid is 4, and nonverbal autistic. He got a bug at preschool 27/10. He was sick once or twice every day (well, mostly night) until 1/11, and had two A&E visits plus a brief spell on the children's ward during half term week, as by that point getting dehydrated. Thought we'd got through it (though 3/11 the baby started with it, so we know it was a bug, but he was fine by next day).
Anyway Monday we went back to school, because he'd been fine, and Monday night he was sick after tea. Just the once, and then slept okay (ha! slept okay by his standards, anyway), and then was entirely fine for the remainder of the week. Back to school yesterday, still fine... Tonight, threw up in bed about 11pm, then like eight more times, and has only just stopped and finally fallen asleep.
Now, the doctors say it's 'just a bug'. And clearly it is a bug, otherwise the baby wouldn't have had it. All his preschool teachers had it over half term. But nobody except us seems concerned as to why he can't shake it off - this is his second relapse now and it's been over a fortnight since it all started. He's so fed up too. He screams a terrible sound like you've never heard when he's being sick, it's like his worst sensory nightmare, and it's unbearable to see him so distressed. But when he's not being sick, he's fine - playing, bouncing, laughing, eating. No temp. Doesn't seem to be in pain (but very possibly could be - he doesn't have typical pain responses, so for example he completely ignores quite nasty bumps, but screams like he's wounded if you touch his hair. And he can't talk.
I've called 111 AGAIN tonight and they've said they'll arrange an out of hours appointment in the morning for him. But honestly they just sound a bit fed up of us at this point, like, they've told us it's a bug and we just keep coming back to them. And it's so hard to balance wanting to have him checked over for his own safety, with not distressing him when he's so poorly - he HATES hospitals and doctors with a burning passion. But I really am becoming concerned, this just seems such a long time to still keep being sick, and the poor little mite is so done with it himself. Not really sure what we do next.
