Register for books! Register for diapers! Feeding gadgetry alone could add tens of items to the list--I found all kinds of cute bowls w/ lids, suction cup mats, portable restaurant feeding placemat, 2-3 good quality bibs, 2-3 sizes of spoons (I didn't know they were sized for baby's mouth or handles for self feeding), those "ice cube" trays for homemade babyfood....the list goes on. My registry is really spartan, too, if you take away the books & feeding items since we bought our own crib, dresser, mattress, monitor, mei tai, Boppy, pack n play & stroller either through Craigslist, eBay or the cheapest online retailers. I didn't register for a swing, either.
The bottom line for me is that if you don't have enough items for your guests to get an idea about your tastes, you'll end up w/ all kinds of random crap--and even if you CAN return it to various stores (some people take off ALL tags/stickers/barcodes), you'll be driving all over God's creation trying to do it w/ random store credits at a million places.

"You've probably heard the expression 'I believe in God, just not organized religion.' I don't think people would say that if the church truly lived like we are called to live. The expression would change to 'I can't deny what the church does, but I don't believe in their God.' At least then they'd address their rejection of God rather than use the church as a scapegoat."
