Breastfeeding?!

Rochelle • I`m a nurse in illinois with a 4 year old who`s dreaming of a being a big sis. I`ve been with my husband for 9 years and we`ve been trying to conceive for over 2 years. On our 2nd round of clomid.
I'm 5.5 months prego with my 2nd and I wasn't able to bf my first d/t an emergency c-section and other things. What do I need to get to be successful?! Supplies, clothing, etc? Also, best pump! Thanks for your help!
