I currently have a 3 yr old and a baby due in June. I need a new diaper bag because I stopped carrying one over a year ago. I really wanted a backpack style because I'm very petite and find most bags too large for me to carry. I am leaning toward a Ju Ju Be BFF but I didn't know how large it is. It seems a little smaller than the Petunia Pickle Bottom which was huge on me. Does anyone have any other suggestions for a backpack style diaper bag for someone who is small framed? Thanks!
