Yes I'd be ok with it (on the understanding that it's not going to happen very much once bubs is born ) provided you have both worked out a plan B. ie - not only someone you can call but someone who can go and get him if he's not answering phone, etc. Also I'd be negotiating the extent of the drinkies, ie a few leaves you able to sober up in an hour or so but any more than that (ie getting sh*tfaced) is not acceptable.
