DD1 (4) has just vomited (she has a sore throat and a cold but isn't really ill). This is the third bout of vomiting she's had since the start of December, missing two days of school after each occasion on account of the 48 hour rule (+a day extra last time as she threw up again on day 2). I'm a primary school teacher, albeit KS2, but I can't say I know of many, if any, kids who have been off this frequently with a DV kind of bug. Should I be worried about how often she's being sick, or is it to be expected at her age / this time of year? We're lucky in as much as we both work part time so sick kids don't impact on either of us going to work, but I wonder if I should have her looked at? Anyone else's children picking up one tummy bug after the other?
