Etiquette on baby shower for the second?

[heather]

I know of a person that is having her second child at the end of March. Her children will be 2 and half years apart. Both are the same sex and she is using the same initals, because she monogrammed everything for the first. I recently looked at her registery and found that she has asked for almost every single thing at the store, and I know over 75% of the stuff she asked for she already has from the first child. I really feel that in this situation it is rude to ask for things you have and don't need. She is a very materialistic person! I would like outside opinions on this please!
I am not cheap, but I do think that she is asking for things not just for the baby but for herself. She has over 200 things picked out on her registery and I know for a fact she has all the basic stuff expect diapers and wipes.
. She has asked for things that she already has..such as a rocker..I dont care how many kids you have, you arent gonna move from rocker to rocker with each child.
