I don't think people seem to realize that there is a market out there for almost any product. Especially if its the best product on the market for that purpose. You have a bunch of different baby carriers - look at baby bjorn. It does not mean everyone else should stop making baby carriers because there is already one out there. In addition, there are baby slings. I have a couple of kids and would NEVER have used a baby sling but that does not mean no one else would. obviously someone else does because there are a bunch of different baby slings out there. My point is ... how many times have you walked through a store and said to yourself "who in their right mind would buy that product?" Someone does or else it wouldn't be in the store.
