10yo DS2 had been told not to take conkers in to school.
Granny and DS2 have been having a whale of a time collecting conkers, stringing them up and playing each other. (Granny seems to be at a advantage...I suspect foul play involving vinegar and baking)
Now DS2 had been told by his class teacher conkers are not allowed in school, which DS is happy to respect.
Is this normal is schools these days? Are conkers a health and safely hazard?
