I want a new diaper bag before my 2nd one arrives. I have a son that will be 2 when the new one arrives, and he isn't potty trained yet. I love the Ju Ju Be bags, but I don't know if I need the BFF or Be Prepared. I think I tend to pack everything. Right now I'm at the point where I want to bring less, but with another one coming, I know I'll be packing a lot for her. Any advice will help. Thanks!
