yay or nay for guests? (not for grandparents who ask for one)

we went to a bday part a cpl months back, where the mom told us about the lil boy's wish list on TRU-- it was easy to find a gift in our price range and we liked it.

DH suggested doing one for LO's first bday and I decided against it because I didn't want to put off our guests that we expected anything more than their presnece at the party. DH said it wasn't rude because they're all wanting to bring gifts so this helps us on the back end of having to return/etc. (Mind you I'd be doing all the returns/exchanges :P)

I didn't include one in our invite.

What do you think?
