EBF to pumping too???

Montanna • Fiancé 💍 Mama 🤱🏼+🤰🏼 💙💗

My little man is 1 month this Thursday and I’ve been exclusively breastfeeding him on demand the last four weeks. I want to start pumping and getting a little bit of a stash but don’t know how to start?? I’m a FTM and don’t know anything about saving breast milk or anything along those lines. I want to still mainly breastfeed him but have some pumped milk for when I may need a break or if I’m not around. I’m also going back to college at the end of August and he will be with me during most classes but in case he’s at grandmas or something. Do I wait to start pumping? Also how do you thaw breast milk? Help please😂
