All-in-one pump/diaper bag

Help me out working moms!

I just went back to work last week and my daughter started daycare. I have so much stuff to carry back and forth and it's terrible! I have her diaper bag with bottles and stuff for daycare, I have a bag for my pump/parts/bra, a cooler bag for storing bottles at work, and my lunch bag.

I need to condense! I'd love to have one bag that would fit my pump/accessories, her diaper bag contents, and my wallet/phone/keys. Bonus if it could fit the cooler bag with bottles, but I realize I might be asking too much.

What's your favorite all-in-one diaper and pump bag?!?!
