Welcome to YT and congrats on getting Frankie! Can't wait to see pics of the little guy
I can relate to your wife...sometimes, that puppy comes along that you just KNOW is "the one."
Definitely keep some Nutrical on hand and watch for signs of hypoglycemia (do a search so you'll know the symptoms). Hopefully you won't even have to worry about it with Frankie, but best to be prepared because the little tinies can go down super fast.
Again, post some pics when you get the chance
