Hi everyone. I've just rented a Symphony (for personal comfort reasons, my PIS was making me sore - we'll see if the new pump helps). Obviously I cannot carry around that enormous hard case around. I found our old backpack-style diaper bag it fits nicely in. But now I don't have room for my pump parts (like the top part of the PIS backpack). I used to leave my rinsed-out parts in there to let them dry, the empty bottles, etc. I guess I have to get ANOTHER bag (now I will leave the house with, like, 7 bags) for the pump parts. What works best? A mesh-style "ditty" bag? A plain old ziploc bag? Any tips?
