Perhaps my view of registries is different from others (?) but I don't think that your sister-in-law is "expecting" anything from anyone. The point of making a registry is that there are times in life where people want to buy you things, like when you have a baby. They would ideally like to buy you something you would really like to have and need and enjoy. So, you make a list to give those people ideas. And, since Grandma Jane is likely to spend more money on you and baby than your co-worker, you put a variety of items on your list. Also, especially if this is her first baby, she is probably just really excited about all the cute things for her nursery that she found at the store and wants everyone else to see the cute things that she would have in her ideal nursery. I enjoy looking at other's registries just to see their tastes and excitement emerge. I used to work at Babies 'R' Us, and though I saw many expectant moms walk around with comments of "Oh! Look how cute this is!" I never once heard one say "Oh! Lets put this on the registry so someone will buy it for us!" And, though I do live in Utah now, I grew up far from here, so I don't think it is just a Utah thing. Just love her and forgive her this little faux pax (or however you spell it...) as you see it.
