My partners ex has returned today from the Canary Islands with their 2 kids after a 4 day break. It’s our weekend to have them, she dropped the 6 year old DD off an hour ago, she has since said to my partner on the phone that her eldest is now in isolation and not going to school because he “has the sniffles” - is it just me or is it irresponsible for her to send the 6 year old to us for our weekend??
