Is it ok to sign up for a baby registry?

Old rules of etiquette would say that it is a definite no-no to tell your guests what to bring (besides assigning a certain theme). But baby gift registries are becoming more and more useful and more and more popular. Go ahead and sign up for a baby gift registry. You can include a note in the invitation that says where you are registered, but it looks best if you can get the word around by word of mouth. Be sure that the cost of items covers a wide range. You can also propose that guests chip in for one, larger item.
