How to exclusively pump

Kayla • Nora Elyse 12/8/17 💕

I’m a FTM and am wanting to start pumping exclusively. I am 11 days postpartum and have been breastfeeding on demand.

I feel pretty clueless when it comes to pumping breastmilk so can anyone give guidance on how to start? Are there any good websites I can go to for reference?
