Pumping/bottle help

Breanna • little man born 02/2019 💙

Hey! FTM here— can someone please explain to me how pumping works? Like how does it go from in the pump to baby’s mouth? I’ll be breastfeeding but would like to also pump so my husband can give a bottle or two at night or if I want/need to leave the house without baby, or when my parents take him. I get how to physically use the pump to get the milk out but what happens after? I feel so dumb!
