I use Lansinoh, until I had so many issues my OB had to prescribe an RX nipple cream..it was expensive, but it helped so much...can't remember what it is called, but keep that in mind if you end up having nipple soreness issues.
Since DS had some blood sugar issues right after birth due to my GD, we had to supplement with formula, so the nurses had me pump to help stimulate my milk production, so you may want to bring your pump...my hospital had one for me to use, but as with everything else they charged for it.
I also brought the boppy with me, it really helped since I had a c/s to help keep DS of the incision site while we were in the hospital.
