DS2 (10) has been on and off the loo with an upset tummy since 6am and hasn't gone to school. No sickness or any other symptoms.
When DH rang the school they said there is a bug going round and they are advising parents to keep the children off for 48 hours and don't expect DS back til Monday. 
What if it isn't the bug though? If he's okay for the rest of the day and in the morning can he go in? Don't want to argue with them but don't want him to miss school if possible.
