I am going to get my best friend the Coach diaper bag (which I know she wants) for her shower gift. I would like to load it up with baby stuff that she will need to carry in it. I know nothing about babies or diaper bags, as I have not had children (yet!) I would love some suggestions on stuff to fill the bag with. One thing I know of that is on her registry is the travel baby wipes warmer... what else? TIA!
