Hospital bag question

I'm 34 wks and getting my bag together. I toured the hospital and they told us to bring 2 different bags- one for labor, one for after because the labor rooms are very small. What do you use just for labor? It seems everything I packed was for after delivery, what do you think I'll need for labor? Thanks! This is my 4th baby but my last was a home birth and I didn't pack anything. It's been a long time since I've been in a hospital.
