DS1 projectiled everywhere a week ago, just the once and was slightly off colour with no appetite but was fine a few days later, DS2 presented with the same last Thurs, happy as larry after, not eating much since but ok, he then threw up everywhere again last night. As before he seems fine albeit tired and pale. Should I just feed as normal and hope it doesn't start up again? Is it likely to be the same bug or a new one? And should I send to school tmw? Bloody winter.
