Nurse goodie bags

An

I want to do something nice for the nurses that I will have when I deliver. What is the best option? A big basket full of stuff or individual bags? I don't want late night nurses to get shafted. And when the heck do you give them their bag? As soon as you get there? When they are in the room? When you leave? Also, how many would you make to ensure you had enough? My hospital keeps FTM's for 48 hours. TIA
