Feh. "Whiskey?" probably wouldn't be considered as helpful as one might wish.
If Leslee is staying at home (especially if she is breastfeeding), then she just needs to conform to Catherine's schedule. Leslee sleeps when Catherine sleeps. Then you get to pick up the slack on the housework, cooking & shopping. Don't forget to occasionally pitch in with the changing & feeding schedule.
Of course, once you've adapted to Catherine's schedule, she will change it. (That will go on for the years, BTW.) But eventually she will sleep longer at night and you will be able to get a "normal" night's sleep.
Maybe a little bit of organic red wine to replace the whiskey? Whoever gets to dictate the advice say that pregnant women can have half a glass of red wine nowadays.
