How much is too much? DS (7.5) came down with a nasty sickness bug in the night, he vomitted at least once every hour from 1am. He is still asleep in bed, the being sick stopped at about 6am. He was given sips of water after every episode but really didn't want anything, he's obviously extremely tired and feels awful.
Part of me feels inclined to just let him sleep as long as he likes but another part is quite worried about potential dehydration. We have dioralyte in the house that I can give him when he wakes but it's vile so he may not drink it. When I spoke to him at 7am he didn't want to eat anything at all, understandably. I've not dealt with a bug this bad before in one of them, I'm feeling a bit out of my depth. What do I do next?
