Quoting Unique Mama:" Ohh I would def call the children's father if he is involved in their lives, he needs to know what is going on with his children!"
They live with him. He sends them to my sister's house from Friday night to Monday morning and then she takes them to school and he picks them up that afternoon. I don't know how that's been effected by the school holidays but I'm assuming it's similar. My mum said he picks them up and drops them off at the house and they have to run across the property to get there because he isn't allowed to enter.
