Feeding question.

First time mom so please bare with me. When my little girl arrives I would really like to breastfeed / pump for bottles so daddy can help with feedings. How often do your little ones feed and how much are you to feed them? When breast feeding how do you know they get enough? And when if comes to storing pumped milk how do you store them and for how long? Like I said I’m going to be very new to this so I just want to get an idea. Any answers/tips are very much appreciated!
