You've seen the lists. In fact, you've probably saved them to one of your Pinterest boards. Something to effect of "Hospital Bag Essentials" or "Foolproof Guide to Packing for Baby's Arrival," perhaps? There's plenty of information out there about what you absolutely must have, but once you've had baby you realize there's a ton of crap you really don't need. That's why I asked moms about the one thing they didn't need in their hospital bag.
I'm an OG mama myself, so my bag was an exercise in minimalism. I didn't even pack an extra outfit for myself, so I ended up wearing the clothes I arrived in, home. Still, and even though I kept to packing the basics, I ended up with several items that were completely unnecessary. My baby books told me to pack my own nightgown and robe (more comfortable and better pictures, duh), but my nurse almost immediately made me take them off in favor of a hospital gown. And the little massager I thought I might want? It didn't make it out of the bag (although it was invaluable when my milk came in and my rock hard boobs needed soothing).
Yes, there are items you definitely want to bring, and a lot of it will depend on you as an individual (as well as your hospital or birthing center). Some things, like warm socks with tread, may very well save you. However, in the interest of space and sanity, take it from these moms: there's plenty you can leave at home.
