I have all the same things in my package for the new parents except I also put in some teethers for them, a sweater(of course at this time of the year they don't really need it), and a booklet on training their pup, (alot of new pet parents don't know how to properly train a puppy). As far as the kids, just make sure the parents and kids now how fragile a yorkie is, just jumping out of your arms can severly hurt a yorkie. Sounds like you want the best for your pups and your on the right track!!
