I haven't tried your sling yet but am looking into them. I am a mom of multiples, and let me tell all the nay sayers out there that until you have had multiple babies screaming to be fed at the same time, you may not appreciate these products. I do my best to never prop a bottle and to make sure both of my babies are held when feeding. my in laws chip in a lot of time helping me, but my husband must work, as i did before having twins, and I must sleep at some point. There are just times when it is better to make sure their needs are being taken care of rather than allow them to scream from hunger. it doesn't happen every day, but there are times when both need to be fed simultaneously. Some of you just keep arguing about the dumbness of the sling. Good lord, if you don't like it, post your opinion and go away. You can't win every flipping arguement. Pretty lame when you don't even know the person you are arguing with.
