Awesome to hear about the anniversary sail. She asked you.... a VERY good sign you are doing a great job.
As for life jackets and MOB practice:
I always tell people... "You can't swim when unconscious".
Hit your head as you go over, and all the swimming skill won't save you. Fall overboard in anything more than slight winds and your chances are not great. People new to the game find it surprising how hard it is to even spot a MOB a short distance away, in the water with waves, never mind get them back on board.
I tell my wife we will won't do live MOB practice anymore, since the time she, as a beginner, almost ran over me practising MOB recovery with a 16ft dinghy 20 years ago. I had to put my hands up to push myself away. I jokingly tell people she had it in for me. LOL

(With regular practice, she can now pick up a mooring, or a person, with no drama, under sail)
Cheers,
Roy
PS: Truthfully I have a hard time fully relating to guys who's wives are scared of sailing.
My wife is the exact opposite. She's a bit of an adrenaline junky and more logic driven than emotional.
I've never been able to figure out why there are reportedly so many women who are scared of it.
There are more than a few incompetent "admiral" husbands who yell a lot, but that doesn't explain the rest of the wives/GFs reaction.
In perspective, it's all the more reason to be impressed with your ability to get your wife and kids "on board"
