i used to use a purse as my diaper bag but with a big purse there is too much room for crap. also, i wanted my daughter to recognize her own back since her dad and I would like to have her be able to bring toys when we go out so whatever she can fit in her bag she can bring. she is only a baby still but i think it is great for her to recognize her bag especially when she starts digging in it for snacks and toys.  plus we love that it is a fox because it looks like our pup.  and she really loves it. perfect size, but i am thinking there is no insulated pocket... think that was a little fib, the fabric all feels the same to me.
