Thank you ladies you all have been so much help.
You should take snack just in case you get hungry...I hate hospital food... =(
If you are having a c-section you should take granny panties... also if you plan on breastfeeding, you can take nursing bras. Anything else that you need for entertainment (laptop/books/movies) depending on how long your stay will be. I'm also taking a robe (for walking down the hall), night gowns, your own pads (I hate hospital pads), slippers, flat iron (so if you have visitors), make-up, nursing pads, and anything else you think you will need during your stay.
You don't have to stay in a gown you can bring any clothing that is comfortable for you. I brought pjs and gowns that were easy access since I was breastfeeding. Then for a going home outfit I wore a dress since It was most comfortable. So mainly whatever you find comfortable to wear now is what you should you should bring.
