What would you do?

If you were to drop your one year old off at their dads and they were very visibly hungover, would you leave them there? Long story short, my ex likes a drink and when he goes out, he takes it too far every time. This weekend, he has been away with his mates for a drinking weekend and is still expecting to have our child this afternoon. There has been 2 occasions in the last 3 months where i haven’t deemed him as fit to have her because of alcohol. But the last time, I stopped him from having her because he was clearly hanging out of his ass and I didn’t feel comfortable leaving her. After getting advice from a solicitor, they have basically said that him being hungover isn’t a concern and only if he is drunk/drinking/ or smelling of alcohol should I stop him. The last time was extremely traumatic for our child, left myself and her very shaken up ( a lot happened) so I’m trying to mentally prepare myself for it again. But i just don’t feel that after a heavy weekend away, he is going to be in a fit state to care for our daughter (only has her 7 hours a week). He makes out that his parents are there and that she will be fine but I don’t trust them, never see them so would have to take his word for it. And it just goes against all my instincts to put her in his care when he isn’t fully with it.
