I have 5!!!! & yes I have used them all. One is completely worn out now, one I was just recently given......it's a homemade one with DS name on it & I love it.......currently also almost worn out. We have also used a backpack as DS can carry it. Then there was one I just "had" to have from America & it took til DS was 1 to find it on ebay LOL...love it & will love it for next DS too. Like shoes you can never have too many bags. I was the same with handbags, one for summer, one for winter, one for Weddings LOL. I love bags & the baby bag is now my "handbag" so yep I have lots!!!
