I've gone back to work fairly recently and my DH looks after our DD on his days off. This evening I've come home to find DH in the back garden with one of his close mates having a drink. The pair of them drink heavily together and have been known to stay up all night drinking. I hated it before we had our DC and had it out with DH when I was pregnant. He stopped coming over but now he's back. In fact I'm sure I've seen him about 3 times in the last couple of weeks. I should say that Baby is asleep and the house is clean. However I see that they've got through a whole bottle of lemonade (bought just yesterday) and half a bottle of vodka (bought jointly for a birthday party that didn't get drunk). AIBU to ask him not to have said friend over when he's looking after our DD and for this friend not to drink all our booze?
