My father is a high functioning alcoholic. He drinks and drives. My biggest problem is he takes my son out (2 years old) in the car. He says he has not drank but Im sure I can smell it. I manage to avoid my parents picking him up the majority of the time, but i am having to go back to work and I will have no control over them taking him out in the car whilst they are looking after him. I have told my mother that he is drink driving but she doesn't believe me, or chooses to pretend she doesnt know. I can put him in nursery some of the time but some of the time he is going to be in their care. What can I do to get around this?
