I second the above advice given:
~ nursing tanks/sleep nurse bra's (I ended up not having anything and had my mom go and buy me a nurse bra... it became too small once my milk came in)
~ frozen pads (even if you just use water.... feels sooooo good)
~ lotsa pads, of varying kinds (overnighters, longs, etc)
~ sitz bath, I LOVED my sitz
~ magazines/book, water bottle, and lotsa snacks in a small basket... grab the basket and bring with you wherever you settle down for nursing
~ I struggle with getting enough water: so my rule is to drink, drink, drink while I am nursing
~ embrace the mentality that you earned, deserve, need and is necessary to stay down/in bed as long as you need for full recovery. I was able to do it for almost 2 weeks, THANK YOU dh!
