My poor ds Last weekend he woke suddenly in the night and spent the next 2 days vomitting everything he ate and drank. And for the last few days he has had diarrohea. He seems fine in himself though, no temperature and not acting 'poorly', if anyhting he is just a bit grumpy. He is 20 months old. What shall I do? I'm a bit worried that a bug has lasted this lng, and also that neither dd or I have caught it, so maybe it is something else?
