Just curious if this is quite normal. 4yo has never really had a tummy bug, fortunately. However, just before she comes down with a bug and her temperature starts to spike, most times she will throw up once or twice - it's almost like her first warning sign. So yesterday she threw up twice at nursery, I was all ready for a vomiting bug, but it's just turned into a pretty normal fever illness.
Is this a common thing?
