Don't they give sick leave without any problems? I thought I'd just spend a day at home with the child, but then he threw up two more times. I don't know what he ate, since he was at his mother-in-law's in the village. But his mother-in-law seems to cook fine, maybe it was something store-bought, or he just caught something. And how long is the sick leave usually? He just got back from sick leave on Tuesday and now this again 🤦. The child is a schoolboy, when something like this happened at their kindergarten, I didn't work during those periods.
