Ftm... dumb question

Morganalysss

I’m being induced on the 20th ... what are the rules for storing pumped milk Can I mix in to one container and keep frozen or refrigerated if I’m going to use that day ? Or should each pumping session be separated as well as each Breast if I pump both at the same time ... I’m sorry if this is stupid and I’m not really sure how to ask without sounding dumb if anyone has any advice I’d appreciate it greatly
