Milk Supply/Pumping

Kimmi • Husband & I have been together since 09.02.09💏 Miscarried 08.2012💔 Married 05.30.15💍 TTC 02.2016😥 FINALLY expecting our little rainbow 04.2018😏🌈

I'll be a first time mom in 10 weeks and I would LOVE to be able to breastfeed. So my question is... what are some tips to keep milk supply up? Is pumping necessary? (I'll be home with baby for 4 months till I have to go back to work)
