Bottle feeding breastmilk help 💗

Liliana • 👼🏼👼🏼👧🏻

Hi, I wanted advice on how to properly store milk when going out. I want to start bottle feeding my breastmilk to my baby. I feel like it’s easier for me when I’m out running errands alone with her. But, how do you store milk or even warm up to feed her. I’m a first time mom. I apologize if im ignorant or my question is dumb but I really don’t know how I would do this. Any advice? Thank you so much. 🙏🏽
