He was dehydrated by Sunday evening, so we had a trip to a&e, they observed him for a while and sent us home (alder hey so I'm confident in their care). Vomiting has slowed down enough for him to absorb fluids, so no further dehydration worries at this point, but of course he is very weak, has lost weight, and is in pain (stomach ache, low/fluctuating fever). He can't keep anything down for long, so pain killers are hit and miss. He tries to eat, but keeps vomiting. Drinking plenty of water.
What else can I do? I'm hoping he turns a corner by tomorrow, but need a plan for if he doesn't. It's terrible to see him so ill for so long.
