Hospital bag

I am packing my hospital bag and wanted to know if there is anything you wish you had thought to pack, but didn't. I already have all the essentials (toiletries, extra long charging cables, change for vending machines) but I'm wondering if maybe there is something not-so-obvious that you wish someone had mentioned.

As for baby, I'm essentially just bringing outfits. I know the hospital will supply the diapers and wipes, and I plan to breastfeed. I really shouldn't need anything else... right?!
