Open it on your own and then send a thank-you note in the mail. No sense in lugging unopened gifts to a shower just to take them back home, especially if the gift-giver won't even be there to see you open it.
Oh, thats something I didn't mention - the shower is at my house, so I wouldn't have to take anywhere. I'm NOT hosting my own shower :). My 2 hostesses live far away, are flying in, and I live halfway between my family and my H's family in major city where airport is.
But it sounds like there may already be consensus. Thanks :). I think we'll open them and just display with other baby stuff in Nursery (which ppl will be checking out at shower)
