^Honestly, I wont recommend pumping so early You need to establish your supply first. I started pumping when baby was on his 4-5th week already. Trust me, you will get disappointed with your outcome if you pump so early. 2 of my friends complained to me about pumping only 1oz and they thought they dont't have enough milk when in reality babies dont't really need much on their first few weeks.
It helps if you can attend those breastfeeding workshops in hospitals & also read some online breastfeeding references. You can check kellymom.com
And you can skip the nipple creme. Your breastmilk alone is good enough if ever you get cracked, sore nipples.
