Coop disadvantage

Hello guys, So after very much enjoying bloodborne, I decided to buy this game, and now I would like to play the game with my girlfriend. I have read online that the 2nd player cant pick up certain items and black pearls. Essentially this would mean that the second player would be screwed and be left behind imaging that we start a new game together. Is there any solution to this and what has been your experience with couch coop in regard? Thanks
