I wrote to him and told him that I am not comfortable leaving the children in his care at this time.
And then this just happened:
DD7 revealed something. Her father went to the supermarket with DD7 and DS11 near the campground yesterday. He sent them to another store to buy marshmellows. When they returned, DD7 saw liquor hiding in his trunk. Both children had already thought it suspicious that he sent them away.
This is in violation of the court order.
Never underestimate your children.
