That is such a great idea. We're expecting our first child in November (we found out yesterday that it's a girl). The custom around here is to give the new mom expensive jewelry after she gives birth. Maybe I'll tell DH that I'd like points instead. I think that I'd wear an add-on well, and I'd get much more use out of it, since I'm not a jewelry person.
Have fun with your new points and your new daughter.
