He's very pale and tired. He was just flopping around this evening (although lucid and no temperature) - we've put him to bed now. Do you think he will be alright upstairs on his own? Can children choke on their own vomit ? He was sick about an hour after breakfast, had some water over the course of the morning, slept for 20 mins after lunch (he didn't eat anything), woke and was promptly sick again. Since then he's had a few sips of water but no more vomiting. WWYD?
